At 5.6 feet (1.7 meters), they are the biggest otters in the world and the longest members of the weasel family. The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. [79][80] Bolivia designated wetlands larger than the size of Switzerland as a freshwater protected area in 2001; these are also home to the giant otter. It feeds mainly on fish and crabs, which it tracks down with its sensitive whiskers. They are 1 of 3 species of otter on the continent of South America. [2] Four specific vegetation types occur on one important creek in Suriname: riverbank high forest, floodable mixed marsh and high swamp forest, floodable low marsh forest, and grass islands and floating meadows within open areas of the creek itself. 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. The giant otter is clearly distinguished from other otters by morphological and behavioral characteristics. Fluffy fur and husky profile. [39] One fight was directly observed in the Brazilian Pantanal in which three animals violently engaged a single individual near a range boundary. [26] Its velvety feel makes the animal highly sought after by fur traders and has contributed to its decline. The World Conservation Union (IUCN) considers the species' presence in Argentina and Uruguay uncertain. Parasites, such as the larvae of flies and a variety of intestinal worms, also afflict the giant otter. Giant River Otter. Poaching has long been a problem. [54] The giant otter seems to be opportunistic, taking whatever species are most locally abundant. [33] Duplaix identified nine distinct sounds, with further subdivisions possible, depending on context. Group members share roles, structured around the dominant breeding pair. The Giant River Otter has the shortest coat of any otter on the planet. It feeds mainly on fish and crabs, which it tracks down with its sensitive whiskers. [51] Other causes of death include accidents, gastroenteritis, infanticide, and epileptic seizures. Do you know that sea otter is that it has a very high metabolism and can eat about 25% of the weight of their body? Giant otters adopt communal latrines beside campsites, and dig dens with a handful of entrances, typically under root systems or fallen trees. 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. Groups of about 5 to 10 otters live together in dens or burrows beside a river. [42] While not rare among large predators in general, intraspecific aggression is uncommon among otter species; Ribas and Mourão suggest a correlation to the animal's sociability, which is also rare among other otters. [2] In the former, investigation has shown thinly distributed population remnants. You can also find the Neotropical Otter and the Marine Otter in South America. [55] If fish are unavailable, it will also take crabs, snakes, and even small caimans and anacondas. Females appear to give birth year round, although in the wild, births may peak during the dry season. [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. [2] Given local extinctions, the species' range has become discontinuous. The threat has been exacerbated by the otters' relative fearlessness and tendency to approach human beings. All otters produce vocalizations, but by frequency and volume, the giant otter may be the most vocal. The giant river otter is the longest member of the Mustelidae or weasel family. Schoolchildren, however, had a more positive impression of the animal. Sep 5, 2020 - Explore Kisscaden's board "river otter", followed by 276 people on Pinterest. The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. [58] The spectacled caiman is another potential competitor, but Duplaix found no conflict with the species in Suriname. The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs. Big, black, triangular “teddy bear” nose. Almost always swim in a dog paddle, almost never swim on their backs. Marine & Freshwater Environmental Education. [2] Typically, loggers first move into rainforest, clearing the vegetation along riverbanks. 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. [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. [4] They are weaned by nine months and begin hunting successfully soon after. Group sizes are anywhere from two to 20 members, but likely average between four and eight. Two subspecies are currently recognized by the canonical Mammal Species of the World, P. b. brasiliensis and P. b. paraguensis. The marine otter is larger than the Eurasian Otter. [65] One difference in behavior was seen in the country in 2002: the normally inquisitive giant otters showed "active avoidance behavior with visible panic" when boats appeared. [12] Later gene sequencing research on the mustelids, from 2005, places the divergence of the giant otter somewhat later, between five and 11 million years ago; the corresponding phylogenetic tree locates the Lontra divergence first among otter genera, and Pteronura second, although divergence ranges overlap.[20]. Species: Neotropical, Southern River, Marine and Giant Otter. [57] In some cases, supposed cooperative hunting may be incidental, a result of group members fishing individually in close proximity; truly coordinated hunting may only occur where the prey cannot be taken by a single giant otter, such as with small anacondas and juvenile black caiman. This one was quietly slipping back into the water after being on the riverbank taking a rest. [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. But when it cannot find food in the water, it has been known to go after andaconda’s! An average giant otter will weigh between 22 and 32kg (49-71lbs).. Hums and coos are more reassuring within the group. They appear in a fish poisoning legend where they assist a man who has wasted his sexual energy, creating the anacondas of the world from his distressed and extended genitals. Threats: habitat d… 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. [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. [62] Giant otters may adopt preferred locations perennially, often on high ground. The main diet of the otter is made up of fish and crustaceans. )[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. The Giant River Otter was nearly hunted to extinction during the 1950’s and 60’s and the Giant River Otter was so close to extinction that ion 1979 just twelve of them remained. 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. [78] In a report for World Wildlife Fund in 2002, Duplaix was emphatic about the importance of Suriname and the other Guianas:[59] .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}. In Brazil it is known as ariranha, from the Tupí word ari'raña, meaning water jaguar (Portuguese: onça d'água). [56], The species can hunt singly, in pairs, and in groups, relying on sharp eyesight to locate prey. This is why so many conservation efforts have been made to save the Otter of the Sea.​. [38] The Giant River Otter is peacefully eating an Amazonian tropical freshwater fish. 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. The park harbors many endangered plants and animals, including the giant otter, and holds the world record for mammal diversity. 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 species is territorial, with groups marking their ranges with latrines, gland secretions, and vocalizations. The giant otter is large, gregarious, and diurnal. Jaguars have a diet of primarily caimans and capybaras … but these sisters seem intent on possibly broadening their dietary horizons. [51] This sensitivity is matched by a strong protectiveness towards the young. They are found along fresh water rivers, lakes and streams. Defence against intruding animals appears to be cooperative: while adult males typically lead in aggressive encounters, cases of alpha females guarding groups have been reported. [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. 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. The IUCN lists Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, and Venezuela as current range countries. [63], Research generally takes place in the dry season and an understanding of the species' overall habitat use remains partial. [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. 59. The giant otter needs to eat 6½lb (3kg) of fish each day. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. The neotropical otter is active during twilight and darkness, reducing the likelihood of conflict with the diurnal giant otter. [57] Carter and Rosas have found captive adult animals consume around 10% of their body weight daily—about 3 kilograms (7 lb), in keeping with findings in the wild. The species was listed as endangered in 1999 and wild population estimates are typically below 5,000. [59], Local people sometimes take pups for the exotic pet trade or as pets for themselves, but the animal rapidly grows to become unmanageable. 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. 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. [72] Specific threats from human industry include unsustainable mahogany logging in parts of the giant otter range,[69] and concentrations of mercury in its diet of fish, a byproduct of gold mining. 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. The survival of the giant otter populations in the Guianas is essential to the survival of this endangered species in South America. 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 . April 26, 2018 - This is a giant otter. One report found between three and eight campsites, clustered around feeding areas. 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). [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. 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. The giant otter has a handful of other names. They give birth within these dens during the dry season. Well suited for an aquatic life, it can close its ears and nose while underwater. They are also downright scary-looking. These mammals have whiskers, which they use to spot their prey by detecting vibrations in the water. River otters: Dark brown. Sleek fur and skinny profile. [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. [16] The ears are small and rounded. Giant river otters are very sociable and live in families of between 3 – 10 individuals that hunt together. It’s afternoon, the giant otter shrew looks around at nature around them, this particular shrew has just barely escaped capture from human researchers, and now has decided that it was going to hunt. Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. Ecotourism also presents challenges: while it raises money and awareness for the animals, by its nature it also increases human effect on the species, both through associated development and direct disturbances in the field. 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. They are also downright scary-looking. Giant river otter cubs are born totally covered in fur. The Otter of the Sea floats amongst its raft of colony members. 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. 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. Weights are between 26 and 32 kg (57 and 71 lb) for males and 22 and 26 kg (49 and 57 lb) for females. In the wild, it has been suggested, although not systematically confirmed, that tourists cause similar stresses: disrupted lactation and denning, reduced hunting, and habitat abandonment are all risks. 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. Long, serpentine tail. [25] The nose (or rhinarium) is completely covered in fur, with only the two slit-like nostrils visible. An IUCN study in 2006 suggested 1,000 to 5,000 otters remain. The Giant River Otters social life is heavily reliant of other otters, as they do everything together, from hunting, playing, sleeping, and traveling together! Their long tail may add as much as 70cm (28in) to this body length. Statistics show between 1959 and 1969 Amazonian Brazil alone accounted for 1,000 to 3,000 pelts annually. The Otter of the Sea floats amongst its raft of colony members. Gymnotids, such as the electric eel, and the large silurid catfish are among aquatic competitors. [15] Biologist Nicole Duplaix calls the division of "doubtful value". 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. Researchers emphasize that even between groups, conflict avoidance is generally adopted. 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. Its distribution has been greatly reduced and is now discontinuous. [69] The animal's relatively late sexual maturity and complex social life makes hunting especially disastrous.[13][70][71]. Appearance. They can grow to almost six feet in length. In other otter species, vision is generally normal or slightly myopic, both on land and in water. Early travelers' reports describe noisy groups surrounding explorers' boats, but little scientific information was available on the species until Duplaix's groundbreaking work in the late 1970s. [27] Unique markings of white or cream fur color the throat and under the chin, allow individuals to be identified from birth. They are often referred to as the river wolf and are the largest otters in the world. The Otter of the Sea is very social and travels in 'rafts' of otters. See more ideas about river otter, otters, otter love. [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. Giant Otters are found in the Rainforests of South America. [28] The legs are short and stubby and end in large webbed feet tipped with sharp claws. Though the fur trade is … [43][44] Within groups, the animals are extremely peaceful and cooperative. [47][48] They then search for new territory to begin a family of their own. The giant otter is a highly social animal and lives in extended family groups. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. 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. A study of five indigenous communities in Colombia suggests native attitudes toward the animal are a threat: the otters are often viewed as a nuisance that interferes with fishing, and are sometimes killed. 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. [66] While the two species are sympatric (with overlapping ranges) during certain seasons, there appeared to be no serious conflict. [4] Other sources have found greater intervals, with as long as 21 to 33 months suggested for otters in the wild. Other water habitats include freshwater springs and permanent freshwater lakes. The two predators are such worthy foes, there's only one recorded case of a jaguar killing a giant otter. [24] The fur is extremely dense, so much so that water cannot penetrate to the skin. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[4]. 5. [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. [68], The animal faces a variety of critical threats. [37] The species has likely been extirpated from southern Brazil, but in the west of the country, decreased hunting pressure in the critical Pantanal has led to very successful recolonization; an estimate suggests 1,000 or more animals in the region. [51], The giant otter is very sensitive to human activity when rearing its young. [12] Both species also show strong pair bonding and paternal engagement in rearing cubs. [17] (The North American river otter (Lontra canadensis) is the fourth Lontra member.) [13] Total population numbers are difficult to estimate. [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. Giant otter muzzles are short and sloping and give the head a ball-shaped appearance. Giant otters are the largest of any otter in the world growing up to 1.8m. Besides having good eyesight, river otters also use their sensitive whiskers to detect motion in the water. Some sea otters might get heavier. They are extremely easy to hunt, being active through the day and highly inquisitive. The giant otter or giant river otter[3] [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. The implementation of CITES in 1973 finally brought about significant hunting reductions,[13] although demand did not disappear entirely: in the 1980s, pelt prices were as high as US$250 on the European market. The Giant River Otter now unconscious because it did not have the use of tools on its side. Incorrect descriptions of the species have led to multiple synonyms (the latter subspecies is often P. b. paranensis in the literature). [34] An analysis published in 2014 cataloged 22 distinct types of vocalization in adults and 11 in neonates. [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. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. [64] Pups are more vulnerable, and may be taken by caiman and other large predators,[51] although adults are constantly mindful of stray young, and will harass and fight off possible predators. When in the water, the giant otter faces danger from animals not strictly preying upon it: the electric eel and stingray are potentially deadly if stumbled upon, and piranha may be capable of at least taking bites out of a giant otter, as evidenced by scarring on individuals. This photograph of a Sea Otter feeding on a black mussel was captured in Kenai Fjords National Park, Alaska (8/13). Many conservation group search for a key to saving the species, but it is hard when fishermen find them to be nuisance. Group hierarchies are not rigid and the animals easily share roles. 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. [14] P. b. paraguensis is supposedly smaller and more gregarious, with different dentition and skull morphology. [12], The otters form the subfamily Lutrinae within the mustelids and the giant otter is the only member of the genus Pteronura. Prey chase is rapid and tumultuous, with lunges and twists through the shallows and few missed targets. [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. [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. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. Other species that prey upon similar food resources include the caimans and large fish that are themselves piscivores. Run easily on land. The animal is susceptible to a variety of diseases, including canine parvovirus. [69] While still present in a number of north-central countries, giant otter populations are under considerable stress. Read More. Habitat degradation and loss is the greatest current threat. 8.) 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. [65], Even if without direct predation, the giant otter must still compete with other predators for food resources. [75], The giant otter has lost as much as 80% of its South American range. [48] Females have a gestation period of 65 to 70 days, giving birth to one to five pups, with an average of two. [59] It occurs in freshwater rivers and streams, which generally flood seasonally. Otters (Sea, Giant & River) A collection of otter images from diverse locations. The giant otter seems to choose clear, black waters with rocky or sandy bottoms over silty, saline, and white waters. [81], Throughout its range, the giant otter interacts with indigenous groups, who often practice traditional hunting and fishing. Other threats to the giant otter include conflict with fishermen, who often view the species as a nuisance (see below). [61] They clear significant amounts of vegetation while building their campsites. [59] Duplaix identified two critical factors in habitat selection: food abundance, which appears to positively correlate to shallow water, and low sloping banks with good cover and easy access to preferred water types. [60], Giant otters use areas beside rivers for building dens, campsites, and latrines. The estrous cycle is 21 days, with females receptive to sexual advances between three and 10 days. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [18] Giant otter fossil remains have been recovered from a cave in the Brazilian Mato Grosso. Females are smaller at 1-1.5m (3.3-4.9ft). 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 species was so thoroughly decimated, the number dropped to just 12 in 1971. The Otter of the Sea as a pup almost got snatched up by a bald eagle in Alaska. An analysis of dry season range size for three otter groups in Ecuador found areas between 0.45 and 2.79 square kilometres (0.17 and 1.08 sq mi). As human activity expands, giant otter home ranges become increasingly isolated. [85] A Maxacali creation story suggests that the practice of otter fishing may have been prevalent in the past. Find out more about this beautiful mammal. 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.
