[25] Guard hairs trap water and keep the inner fur dry; the guard hairs are approximately 8 millimetres (one-third of an inch) in length, about twice as long as the fur of the inner coat. The species was listed as endangered in 1999 and wild population estimates are typically below 5,000. [51], The giant otter is very sensitive to human activity when rearing its young. [24] Giant otters use these marks to recognize one another, and upon meeting other otters, they engage in a behavior known as "periscoping", displaying their throats and upper chests to each other. Groups of about 5 to 10 otters live together in dens or burrows beside a river. VS The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. The animal is susceptible to a variety of diseases, including canine parvovirus. The giant river otter is the longest member of the Mustelidae or weasel family. Limits on the number of tourists at any one time, fishing prohibitions, and a minimum safe distance of 50 metres (164 ft) are proposed to offer further protection. Here’s why. The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. Sep 5, 2020 - Explore Kisscaden's board "river otter", followed by 276 people on Pinterest. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. Carter and Rosas, however, rejected the subspecific division in 1997, noting the classification had only been validated once, in 1968, and the P. b. paraguensis type specimen was very similar to P. b. Females appear to give birth year round, although in the wild, births may peak during the dry season. [14] P. b. paraguensis is supposedly smaller and more gregarious, with different dentition and skull morphology. Create your own unique website with customizable templates. [72] Duplaix relates the story of an Arawak Indian who took two pups from their parents. Giant Otters have evolved independently from the sea and the river otters in the continent of South America. The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. Additionally, sea otters spend the vast majority of their lives in the water, while river otters spend most of theirs on land, venturing into the water for tasks like hunting for food and traveling. Giant Otters are found in the Rainforests of South America. Other species that prey upon similar food resources include the caimans and large fish that are themselves piscivores. [13], Adult giant otters living in family groups have no known serious natural predators, however there are some accounts of black caimans in Peru and yacare caimans in the Pantanal preying on giant otters. The animal's well-muscled tail can add a further 70 cm (28 in) to the total body length. The Otter of the Sea was almost trapped to extinction through the 1800's because of their desirable fur coats. River otters: Dark brown. It feeds mainly on fish and crabs, which it tracks down with its sensitive whiskers. [46], Details of giant otter reproduction and life cycle are scarce, and captive animals have provided much of the information. [69] The animal's relatively late sexual maturity and complex social life makes hunting especially disastrous.[13][70][71]. The giant otter subsists almost exclusively on a diet of fish, particularly characins and catfish, but may also eat crabs, turtles, snakes and small caiman. The giant river otters have also been noted to feed on small anacondas and caimans. The giant otter or giant river otter (Pteronura brasiliensis) is a South American carnivorous mammal. Poaching has long been a problem. Check this one out: Giant otter with fish. The giant otter is large, gregarious, and diurnal. Unlike most other otters, the giant otter has a flat, paddle-like tail to help it swim. The giant otter (Pteronura brasiliensis), known through much of its range as the 'river wolf', is one of South America's top carnivores and is the largest of the otter species in terms of total length.The muscular, sinuous body is covered with velvety, brown fur, which is dense and water-repellent. [73][74] Water pollution from mining, fossil fuel extraction, and agriculture is a serious danger; concentrations of pesticides and other chemicals are magnified at each step in the food chain, and can poison top predators such as the giant otter. The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [13] Total population numbers are difficult to estimate. In Brazil it is known as ariranha, from the Tupí word ari'raña, meaning water jaguar (Portuguese: onça d'água). The smaller hairs help trap air next to their skin thus they never really get wet. The Giant River Otter is found to be one of the most dangerous water dwelling creatures in the Guianas, where the locals have given it the name “river wolf”. The giant river otter has become rare or nonexistent over most of its range. Many people don’t know the difference between sea otters and river otters — but, with a little info, you’ll be able to tell right away. Feb. 04. They are found along fresh water rivers, lakes and streams. The IUCN listed the giant otter as "endangered" in 1999; it had been considered "vulnerable" under all previous listings from 1982 when sufficient data had first become available. You can also find the Neotropical Otter and the Marine Otter in South America. In seasonally flooded areas, the giant otter may abandon campsites during the wet season, dispersing to flooded forests in search of prey. The giant river otter is a great reminder that lovability can come in all sizes. The giant otter is clearly distinguished from other otters by morphological and behavioral characteristics. 7.) [65], Even if without direct predation, the giant otter must still compete with other predators for food resources. Jaguars have a diet of primarily caimans and capybaras … but these sisters seem intent on possibly broadening their dietary horizons. [85] A Maxacali creation story suggests that the practice of otter fishing may have been prevalent in the past. )[72] The animal sometimes drowns in nets set across rivers and machete attacks by fishermen have been noted, according to Duplaix, but "tolerance is the rule" in Suriname. [59] Otters do not visit or mark every site daily, but usually patrol all of them, often by a pair of otters in the morning. They give birth within these dens during the dry season. [63], Research generally takes place in the dry season and an understanding of the species' overall habitat use remains partial. [65], The species has also appeared in the folklore of the region. [66] While the two species are sympatric (with overlapping ranges) during certain seasons, there appeared to be no serious conflict. [83] A Ticuna legend has it that the giant otter exchanged places with the jaguar: the story says jaguar formerly lived in the water and the giant otter came to the land only to eat. Weights are between 26 and 32 kg (57 and 71 lb) for males and 22 and 26 kg (49 and 57 lb) for females. [51] Other causes of death include accidents, gastroenteritis, infanticide, and epileptic seizures. [16], An extinct genus, Satherium, is believed to be ancestral to the present species, having migrated to the New World during the Pliocene or early Pleistocene. See more ideas about river otter, otters, otter love. One report suggests maximum areas 28 m (92 ft) long and 15 m (49 ft) wide, well-marked by scent glands, urine, and feces to signal territory. But when it cannot find food in the water, it has been known to go after andaconda’s! A wavering scream may be used in bluff charges against intruders, while a low growl is used for aggressive warning. The giant otter is diurnal, being active exclusively during daylight hours. Whistles may be used as advance warning of nonhostile intent between groups, although evidence is limited. [2] Typically, loggers first move into rainforest, clearing the vegetation along riverbanks. [53] It feeds mainly on fish, including cichlids, characins (such as piranha), and catfish. [52], The longest documented giant otter lifespan in the wild is eight years. Giant otter muzzles are short and sloping and give the head a ball-shaped appearance. It is also an arguably more essential reminder to not assume that if something is endearing, it is also harmless. [72] A number of restrictions on land use and human intrusion are required to properly maintain wild populations. )[37] The groups are strongly cohesive: the otters sleep, play, travel, and feed together. Fish from the order Perciformes, particularly cichlids, were seen in 97% of scats, and Characiformes, such as characins, in 86%. Almost always swim in a dog paddle, almost never swim on their backs. To reiterate that last point here is some videos of a group of otters against a caiman , pestering a jaguar , and a lone otter chilling with some caimans . The World Conservation Union (IUCN) considers the species' presence in Argentina and Uruguay uncertain. [61] They clear significant amounts of vegetation while building their campsites. Hums and coos are more reassuring within the group. [56], The species can hunt singly, in pairs, and in groups, relying on sharp eyesight to locate prey. The species was so thoroughly decimated, the number dropped to just 12 in 1971. [59], Local people sometimes take pups for the exotic pet trade or as pets for themselves, but the animal rapidly grows to become unmanageable. [69] While still present in a number of north-central countries, giant otter populations are under considerable stress. [46], Suriname still has significant forest cover and an extensive system of protected areas, much of which protects the giant otter. [78] (One researcher has suggested the giant otter is hunted only in desperation due to its horrible taste. Even when told of the importance of the species to ecosystems and the danger of extinction, interviewees showed little interest in continuing to coexist with the species. The fact that it is exclusively active during the day further suggests its eyesight should be strong, to aid in hunting and predator avoidance. [16] The ears are small and rounded. These are two jaguar sisters named Medrosa and Jaju. Other researchers suggest approximately 7 square kilometres (2.7 sq mi) and note a strong inverse correlation between sociality and home range size; the highly social giant otter has smaller home range sizes than would be expected for a species of its mass. [47] Pups open their eyes in their fourth week, begin walking in their fifth, and are able to swim confidently between 12 and 14 weeks old. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[4]. The smaller neotropical otter is far more shy, less noisy, and less social; at about a third the weight of the giant otter, it is more vulnerable to predation, hence, a lack of conspicuousness is to its advantage. [47] Study of captive specimens has found only males initiate copulation. Females are smaller at 1-1.5m (3.3-4.9ft). It is regulated internationally under Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES): all trade in specimens and parts is illegal. The giant otter has a handful of other names. [81], Throughout its range, the giant otter interacts with indigenous groups, who often practice traditional hunting and fishing. [17] Carter and Rosas found average areas a third this size. The Neotropical otter is the only species which is widespread especially in the central and northern parts of the country. These can become quite extensive, including "backdoor" exits into forests and swamps, away from the water. [7] The Bororó people have a legend on the origin of tobacco smoking: those who used the leaf improperly by swallowing it were punished by being transformed into giant otters; the Bororo also associate the giant otter with fish and with fire. More recently, habitat destruction and degradation have become the principal dangers, and a further reduction of 50% is expected in giant otter numbers within the 20 years after 2004 (about the span of three generations of giant otters). [45], Giant otters build dens, which are holes dug into riverbanks, usually with multiple entrances and multiple chambers inside. Giant river otter cubs are born totally covered in fur. Hunting in shallow water has also been found to be more rewarding, with water depth less than 0.6 metres (2.0 ft) having the highest success rate. This is why the Otter of the Sea obsessively grooms its fur; this rids the fur of foreign material.​, The Otter of the Sea what is known as a keystone species meaning if it becomes extinct the ecosystem around it will collapse because that ecosystem is so dependent on its role in it. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. The sure way to differentiate between the two is the fact that on the surface of the water river otters swim with their belly facing downwards, their bodies almost submerged, but sea otters do backstroke while floating fairly high above the surface of the water. Incorrect descriptions of the species have led to multiple synonyms (the latter subspecies is often P. b. paranensis in the literature). [2] In the former, investigation has shown thinly distributed population remnants. [27] Unique markings of white or cream fur color the throat and under the chin, allow individuals to be identified from birth. April 26, 2018 - This is a giant otter. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. [2] Populations in Bolivia were once widespread but the country became a "black spot" on distribution maps after poaching between the 1940s and 1970s; a relatively healthy, but still small, population of 350 was estimated in the country in 2002. They give birth between August and September, and the young pups emerge for the first time in October and November, which are the months of lowest water and fish concentrations in the dwindling lakes and channels are at their peak. Schoolchildren, however, had a more positive impression of the animal. [47], The giant otter is an apex predator, and its population status reflects the overall health of riverine ecosystems. While revealing of the affection held for the animals, the seizure was a profound blow to the breeding pair, which went on to lose their territory to competitors. [2] It has no serious natural predators other than humans, although it must compete with other species, including the neotropical otter and caiman species, for food resources. They are often referred to as the river wolf and are the largest otters in the world. The Giant river otter has a double layered coat, with a inner coat that is meant as its sense of warmth, and an outer guard layer that covers the inner layer. Logging, hunting, and pup seizure may have led groups to be far more wary of human activity. No institution, for example, has successfully raised giant otter cubs unless parents were provided sufficient privacy measures; the stress caused by human visual and acoustic interference can lead to neglect, abuse and infanticide, as well as decreased lactation. Giant otters are the largest of any otter in the world growing up to 1.8m. In other otter species, vision is generally normal or slightly myopic, both on land and in water. Giant River Otter v.s Giant Otter Shrew. [38] In another instance in Brazil, a carcass was found with clear indications of violent assault by other otters, including bites to the snout and genitals, an attack pattern similar to that exhibited by captive animals. Otters usually eat crustaceans, fish, frog, rodents, and the marine invertebrates with hard shells like crab, mussels, etc. At one point, over 100,000 sea otters called the Pacific Northwest home, but the Washington sea otter population was hunted to extinction at the turn of the 19th century. They noted that the species may be the basal divergence among the otters or fall outside of them altogether, having split even before other mustelids, such as the ermine, polecat, and mink. Among the Achuar people, they are known as wankanim,[7], among the Sanumá as hadami[8][9] and among the Makushi as turara. Other countries have taken a lead in designating protected areas in South America. The Otter of the Sea floats amongst its raft of colony members. In 2004, Peru created one of the largest conservation areas in the world, Alto Purús National Park, with an area similar in size to Belgium. Read More. Here’s why. [2] A significant population lives in the wetlands of the central Araguaia River, and in particular within Cantão State Park, which, with its 843 oxbow lakes and extensive flooded forests and marshlands, is one of the best habitat patches for this species in Brazil. [67] Its smaller prey, different denning habits, and different preferred water types also reduce interaction.[58]. The marine otter is larger than the Eurasian Otter. This species is the largest among all the species of otters in the world, (sea otters , with their more compact body, can weigh considerably more).The males reach a total length of 1.5 to 1.8 m and a weight between 26 and 32 kg.As for females they usually measure 1.5 to 1.7 m in length and can weigh between 22 and 26 kg. Otters (Sea, Giant & River) A collection of otter images from diverse locations. The Otter of the Sea eats 20 to 30 percent of its body weight to keep warm in the cold northern Atlantic Ocean. An IUCN study in 2006 suggested 1,000 to 5,000 otters remain. Gymnotids, such as the electric eel, and the large silurid catfish are among aquatic competitors. [54] The giant otter seems to be opportunistic, taking whatever species are most locally abundant. They are also downright scary-looking. Fish remains were of medium-sized species that seem to prefer relatively shallow water, to the advantage of the probably visually oriented giant otter. [19], Phylogenetic analysis by Koepfli and Wayne in 1998 found the giant otter has the highest divergence sequences within the otter subfamily, forming a distinct clade that split away 10 to 14 million years ago. [49] Males actively participate in rearing cubs and family cohesion is strong;[50] older, juvenile siblings also participate in rearing, although in the weeks immediately after birth, they may temporarily leave the group. You otter know: It’s Sea Otter Awareness Week! [29], At the time of Carter and Rosas' writing, vision had not been directly studied, but field observations show the animal primarily hunts by sight; above water, it is able to recognize observers at great distances. This is why so many conservation efforts have been made to save the Otter of the Sea.​. Species: Neotropical, Southern River, Marine and Giant Otter. The Giant River Otter has the shortest coat of any otter on the planet. This makes it easier for the adults to catch enough fish for the growing young, and for the pups to learn how to catch fish. The Giant River Otters social life is heavily reliant of other otters, as they do everything together, from hunting, playing, sleeping, and traveling together! Next, the tail of a sea otter is short and flattened; a river otter’s tail is long and pointed. Group sizes are anywhere from two to 20 members, but likely average between four and eight. In Cantão State Park, otters dig their reproductive dens on the shores of oxbow lakes starting around July, when waters are already quite low. The threat has been exacerbated by the otters' relative fearlessness and tendency to approach human beings. The giant otter's highly sensitive whiskers (vibrissae) allow the animal to track changes in water pressure and currents, which aids in detecting prey. [26] Its velvety feel makes the animal highly sought after by fur traders and has contributed to its decline. (Pteronura brasiliensis) is a South American carnivorous mammal. The giant otter's hearing is acute and its sense of smell is excellent. [62] Giant otters may adopt preferred locations perennially, often on high ground. brasiliensis. [23] How much food Otter eat each day? Giant otters served as Yaku runa's canoes. ​The Giant River Otter will eat around ten percent of its body weight per day, and is known as a opportunist, preferring to hunt whatever is in abundance in its local river. The Otter of the Sea floats amongst its raft of colony members. Animals And Pets Baby Animals Funny Animals Cute Animals Baby Giraffes Wild Animals Otters Holding Hands Holding Hands Quotes Otter Love. Unbeknownst to the Giant River Otter the Otter of the Sea had traveled all the way from Alaska and quietly snuck up behind it through an estuary. Utreras[61] presumed habitat requirements and availability would differ dramatically in the rainy season: estimating range sizes of 1.98 to as much as 19.55 square kilometres (0.76 to 7.55 sq miles) for the groups. Besides having good eyesight, river otters also use their sensitive whiskers to detect motion in the water. [58] Furthermore, Defler observed associations between giant otters and the Amazon river dolphins, and suggested that dolphins may benefit by fish fleeing from the otters. They are engaged in a standoff near Panthera’s research station in Southern Brazil. [24] The fur is extremely dense, so much so that water cannot penetrate to the skin. The IUCN lists Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, and Venezuela as current range countries. [82], In Suriname, the giant otter is not a traditional prey species for human hunters, which affords some protection. An average giant otter will weigh between 22 and 32kg (49-71lbs).. [38] At least one case of a change in alpha relationship has been reported, with a new male taking over the role; the mechanics of the transition were not determined. The Giant River Otter is peacefully eating an Amazonian tropical freshwater fish. Researchers emphasize that even between groups, conflict avoidance is generally adopted. Males are between 1.5 and 1.7 m (4.9 and 5.6 ft) in length from head to tail and females between 1 and 1.5 m (3.3 and 4.9 ft). [32] Concern over this endangered species has since generated a body of research. Habitat degradation and loss is the greatest current threat. Their long tail may add as much as 70cm (28in) to this body length. Their coats are among the thickest among mammals, the Otter of the Sea needs this to survive in the cold northern Atlantic Ocean. [5] In Spanish, river wolf (Spanish: lobo de río) and water dog (Spanish: perro de agua) are used occasionally (though the latter also refers to several different animals) and may have been more common in the reports of explorers in the 19th and early 20th centuries. 2013. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. [4] They are weaned by nine months and begin hunting successfully soon after. Many conservation group search for a key to saving the species, but it is hard when fishermen find them to be nuisance. [24][30], The species possesses 2n = 38 chromosomes.[31]. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. Big, black, triangular “teddy bear” nose. Article by Jordyn Dominguez. The Otter of the Sea as a pup almost got snatched up by a bald eagle in Alaska. Schenck et al., who undertook extensive fieldwork in Peru in the 1990s, suggest specific "no-go" zones where the species is most frequently observed, offset by observation towers and platforms to allow viewing. [47], Mothers give birth to furred and blind cubs in an underground den near the river shore and fishing sites. [10]The genus name, Pteronura, is derived from the Ancient Greek words pteron/πτερόν (feather or wing) and oura/οὐρά (tail),[11] a reference to its distinctive, wing-like tail. Giant Otters’ Main Characteristics. To help maximize their body heat retention in their cold environment the coats have two layers an undercoat, and then longer guard hairs and they have to give or take 1 million hairs per square inch. It’s been a while since I posted one from the Pantanal in Brazil so here’s a giant river otter — the largest otter in the world. They are 1 of 3 species of otter on the continent of South America. [47] The animal reaches sexual maturity at about two years of age and both male and female pups leave the group permanently after two to three years. The giant river otter (Pteronura brasiliensis) is the largest member of the mustelid family, which includes otters, weasels, and ferrets, and are by far the loudest member of the group.Giant river otters are very sociable and live in families of between 3-10 individuals that hunt together. Giant river otters are very sociable and live in families of between 3 – 10 individuals that hunt together. [39] Duplaix suggests a division between "residents", who are established within groups and territories, and nomadic and solitary "transients"; the categories do not seem rigid, and both may be a normal part of the giant otter life cycle. The Giant River Otter is known for being an apex predator, hunting with speed and efficiency, the Giant River Otter is known to eat anything from a piranha to a even caimans. As human activity expands, giant otter home ranges become increasingly isolated. First, sea otters are two to three times the size of river otters — and, when at the water’s surface, they float on their backs, while river otters swim belly down like most animals. Although generally peaceful, the species is territorial, and aggression has been observed between groups. The smooth-coated otter (Lutrogale perspicillata) of Asia may be its closest extant relative; similar behaviour, vocalizations, and skull morphology have been noted. The reason for this mass genocide was the desirability of its coat, which had a soft velvety feel, the reason for this thick velvety feeling was because of its bottom layer of fur that covered its skin, when dried and taken care of, the pelt was extremely soft. Sea Otter in Morro Bay, Califormia . Neanderthal Hunting Party v.s. The giant otter needs to eat 6½lb (3kg) of fish each day. They can grow to almost six feet in length. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [41] Population densities varied with a high of 1.2/km2 (3.1/sq mi) reported in Suriname and with a low of 0.154/km2 (0.40/sq mi) found in Guyana. Its distribution has been greatly reduced and is now discontinuous. The Guianas are one of the last real strongholds for the species, which also enjoys modest numbers — and significant protection — in the Peruvian Amazonian basin. [77] Duplaix returned to the country in 2000 and found the giant otter still present on the Kaburi Creek, a "jewel" of biodiversity, although increased human presence and land use suggests, sooner or later, the species may not be able to find suitable habitat for campsites. Appearance. [12] Both species also show strong pair bonding and paternal engagement in rearing cubs. [47][48] Research over five years on a breeding pair at the Cali Zoo in Colombia found the average interval between litters was six to seven months, but as short as 77 days when the previous litter did not survive. Using all of its evolutionary traits to its advantage the rare massive 100 pound Otter of the Sea wacks the head of the Giant River Otter with a rock. The main diet of the otter is made up of fish and crustaceans. All otters produce vocalizations, but by frequency and volume, the giant otter may be the most vocal. Males are between 1.5 and 1.7 m (4.9 and 5.6 ft) in length from head to tail and females between 1 and 1.5 m (3.3 and 4.9 ft). The giant otter or giant river otter[3] Giant Armadillo, Giant Flying Squirrel V. Giant Flying Fox, Goat of the Mountain V. Shrew of the Water, Pocket Gopher of the Mountain V. Otter of the Sea, Porcupine of the Cape V. Baby of the Bush, White Faced Capuchin V. Burrowing Bettong, Hairy Nosed Wombat V. Screaming Hairy Armadillo. [55] If fish are unavailable, it will also take crabs, snakes, and even small caimans and anacondas. Two subspecies are currently recognized by the canonical Mammal Species of the World, P. b. brasiliensis and P. b. paraguensis.
