[24] The nose (or rhinarium) is completely covered in fur, with only the two slit-like nostrils visible. 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). The marine otter is really a freshwater otter that has learned to occupy marine environments in South America. [57] The spectacled caiman is another potential competitor, but Duplaix found no conflict with the species in Suriname. The giant otter has a handful of other names. They give birth within these dens during the dry season. recommended for you. Whistles may be used as advance warning of nonhostile intent between groups, although evidence is limited. To notify the family of their presence, otters sharply scream and emerge from the water. Neotropical otter – As the name suggests this is one of the species that lives in warm environments. [71] Specific threats from human industry include unsustainable mahogany logging in parts of the giant otter range,[68] and concentrations of mercury in its diet of fish, a byproduct of gold mining. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. They prefer areas with stable river banks for them to make their dens, which are dug into the mud of the bank sides. The species was listed as endangered in 1999 and wild population estimates are typically below 5,000. All otters live singly, except for a short period, when the female is raising young. Prey species found were also sedentary, generally swimming only short distances, which may aid the giant otter in predation. Ranges from 4.9 ha to 1062.5 ha of sub-Saharan Africa ( except in the sub-Saharan,! The giant otter is … Do otters lay eggs or give live birth? Sea otters can be found close to certain seas near Alaska, Oregon, Washington, British Columbia, and the country of Russia. The implementation of CITES in 1973 finally brought about significant hunting reductions,[12] although demand did not disappear entirely: in the 1980s, pelt prices were as high as US$250 on the European market. A wavering scream may be used in bluff charges against intruders, while a low growl is used for aggressive warning. Giant otters live in the tropical Amazonian region of South America, where the weather is invariably hot and humid, with frequent rain showers. Southern river otter – Is found in the marine and freshwater environments of southern Chile and Argentina. [52] It feeds mainly on fish, including cichlids, characins (such as piranha), and catfish. If you do not live in a warm climate, supplementary heat is necessary for land and water. Within these seas, they are usually found in the vicinity of the shore (which is typically rocky). This is the smallest otter species being only about 11 lbs. Between them, they communicate with different sounds. Years ago, they lived in tropical forests and wetlands, but the presence of human beings has drastically changed this situation. Even in a large group, they rarely have a fight with each other. Fencing needs to extend in-ground because they can also dig out. The sinuous otter is an excellent swimmer and can be seen hunting in wetlands, rivers and along the coast - try the west coast of Scotland, West Wales, the West Country or East Anglia for the best views. Its distribution has been greatly reduced and is now discontinuous. Male river otters do not seem to be territorial, and newly dispersing males may join established male groups. 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. [16] Carter and Rosas found average areas a third this size. [6] All three names are in use in South America, with a number of regional variations. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. Sea otters are found in two areas: The Pacific coasts of Russia and Alaska, and along the central California coast. [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. The fact that it is exclusively active during the day further suggests its eyesight should be strong, to aid in hunting and predator avoidance. Cape clawless otters and Asian small clawed otters love frogs, crustaceans, crabs and mollusks. A fully-grown adult male typically weighs between 57 and 71 pounds (26 and 32 kg). Giant otters live across South America’s Amazon basin, including Tambopata National Reserve, in southeastern Peru. The neotropical otter is active during twilight and darkness, reducing the likelihood of conflict with the diurnal giant otter. [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. [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. The estrous cycle is 21 days, with females receptive to sexual advances between three and 10 days. Otters have their cubs in underground burrows, known as 'holts'. [11] The giant otter shares the South American continent with three of the four members of the New World otter genus Lontra: the neotropical river otter, the southern river otter, and the marine otter. [57] Furthermore, Defler observed associations between giant otters and the Amazon river dolphins, and suggested that dolphins may benefit by fish fleeing from the otters. In other otter species, vision is generally normal or slightly myopic, both on land and in water. Giant otters served as Yaku runa's canoes. The park harbors many endangered plants and animals, including the giant otter, and holds the world record for mammal diversity. Largely as a result of hunting the Giant Otter is now classed as seriously endangered in Colombia, Brazil, Bolivia, Ecuador, Peru, Paraguay and Venezuela. [64], Even if without direct predation, the giant otter must still compete with other predators for food resources. [61] Giant otters may adopt preferred locations perennially, often on high ground. Giant otters are found throughout almost all of South America. Like most other otter species, giant otters come ashore to give birth. [47] Females have a gestation period of 65 to 70 days, giving birth to one to five pups, with an average of two. Fossils of a giant river otter dating back 3.5 Mya have been found ... North American river otters live an average of 21 years of age in captivity, but they can reach 25 years of age. https://www.nationalgeographic.com/animals/mammals/g/giant-otter.html. Let us know on the Wide Open Pets Facebook page! Only giant otters form permanent family groups of 10-15 individuals. The entire group, including nonreproductive adults, which are usually older siblings to that year's pups, collaborates to catch enough fish for the young. Otters are found almost all over the world and in many wet habitats, such freshwater rivers, lakes, oceans, coastlines and marshes. Giant otters regularly feed on piranha, and have also been known to take down alligators. Other threats to the giant otter include conflict with fishermen, who often view the species as a nuisance (see below). Being an apex predator, Giant Otters can hunt alone, in pairs and in groups, mainly hunting fish, however they have been known to hunt anacondas and caimans. Early documentation of skins and live animals suggest that they once grew up to 7.9 feet in length (2.4 m), but such large specimens ceased to exist when the giant otter population began to decline. The river otter is protected and insulated by a thick, water-repellent coat of fur. [32] Duplaix identified nine distinct sounds, with further subdivisions possible, depending on context. Parasites, such as the larvae of flies and a variety of intestinal worms, also afflict the giant otter. At 5.6 feet (1.7 meters), they are the biggest otters in the world and the longest members of the weasel family. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. In Brazil it is known as ariranha, from the Tupí word ari'raña, meaning water jaguar (Portuguese: onça d'água). [14] Biologist Nicole Duplaix calls the division of "doubtful value". [59], Giant otters use areas beside rivers for building dens, campsites, and latrines. An adult North American river otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). 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. They have thick fur that caused them to be hunted to near extinction. © 1996-2015 National Geographic Society, © 2015- Other places you will find them lingering include around rivers, streams, and lakes. These mammals are very agile and feed on small crabs, frogs, and worms. Giant otters have been hunted extensively and wild populations are at-risk. Giant otters live on a diet that almost exclusively consists of fishes and crabs. This South American otter is the world's largest, at some 6 feet long. )[71] 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. After nine or ten months, it is difficult to tell mother from child. Group sizes can vary but have been recorded of … The giant otter's highly sensitive whiskers (vibrissae) allow the animal to track changes in water pressure and currents, which aids in detecting prey. Group members share roles, structured around the dominant breeding pair. If the otter gets all the right nutrients, they should live … [48] Males actively participate in rearing cubs and family cohesion is strong;[49] older, juvenile siblings also participate in rearing, although in the weeks immediately after birth, they may temporarily leave the group. An average giant otter will weigh between 22 and 32kg (49-71lbs). [64], The species has also appeared in the folklore of the region. [72][73] 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. 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. Habitat degradation and loss is the greatest current threat. The North American river otter (Lontra canadensis), also known as the northern river otter or common otter, is a semiaquatic mammal endemic to the North American continent found in and along its waterways and coasts. To spend much more time on land than other otters from Africa, are! [56] 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. How Long Do Otters Live? They den by burrowing into banks or under fallen logs, and establish a home territory that they will aggressively defend. They have very streamlined bodies, with a … [46] 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. It is part of the worlds largest forest. [15] The ears are small and rounded. Otter Habitat and Distribution. The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. The wild animals are found in rivers and creeks in the Amazon basin within the Amazon rainforest. Some of the animals that live in in the rainforest river are manatees, piranhas, giant river otters, capybara, and the Amazon pink river dolphins. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[4]. [31] Concern over this endangered species has since generated a body of research. Giant Otters often baby sit for one another. Giant otters produce 9 different vocalizations and are very loud. [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.

The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs. Otters living in zoos and aquariums are likely to live far past their average life span to almost double or triple years. One report found between three and eight campsites, clustered around feeding areas. Giant Otters might look like any other species of Otter. Fish remains were of medium-sized species that seem to prefer relatively shallow water, to the advantage of the probably visually oriented giant otter. 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. All rights reserved. Logging, hunting, and pup seizure may have led groups to be far more wary of human activity. [40] 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. [71] A number of restrictions on land use and human intrusion are required to properly maintain wild populations. [84] A Maxacali creation story suggests that the practice of otter fishing may have been prevalent in the past. Their long tail may add as much as 70cm (28in) to this body length. The survival of the giant otter populations in the Guianas is essential to the survival of this endangered species in South America. [37] The giant otter is diurnal, being active exclusively during daylight hours. Their aquatic habitats can be both marine and fresh … Please do not trap live otters and then drown them, as it is considered illegal in many states and is a painful way for any animal to die, which can last anywhere up to eight minutes. [2] Typically, loggers first move into rainforest, clearing the vegetation along riverbanks. The giant otter has the shortest fur of all otter species; it is typically chocolate brown, but may be reddish or fawn, and appears nearly black when wet. Do you or anyone you know, live with a pet otter? [60] They clear significant amounts of vegetation while building their campsites. [23] 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. Where do sea otters live? In Cantão State Park, otters dig their reproductive dens on the shores of oxbow lakes starting around July, when waters are already quite low. They tend to set up their nests in the banks of slow moving rivers and lakes as this is safer for their young. In summary: Cage should be outdoors. 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). [57] In addition, solitary animals and young may be vulnerable to attacks by the jaguar, cougar, and anaconda, but this is based on historical reports, not direct observation. The giant otter species eats mainly fishes and crabs. The threat has been exacerbated by the otters' relative fearlessness and tendency to approach human beings. [12] (Larger figures may reflect two or three family groups temporarily feeding together. Basin and arid areas to semiarid regions, to semiarid regions, to semiarid regions, to forested. Being carnivorous, otters feast on a variety of meats from the fish they catch, to crustaceans, mollusks, sea urchins, and amphibians. In Giant Otter, vision is slightly myopic and involves both land and water. One full-year study of giant otter scats in Amazonian Brazil found fish present in all fecal samples. The World Conservation Union (IUCN) considers the species' presence in Argentina and Uruguay uncertain. It can grow up to 1.80 meters (six feet) in length and weigh more than 30 kilograms (70 pounds). 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. Giant otter muzzles are short and sloping and give the head a ball-shaped appearance. [17] Giant otter fossil remains have been recovered from a cave in the Brazilian Mato Grosso. These family-loving animals spend most of their time together. Subadults leaving in search of new territory find it impossible to set up family groups. [46], Mothers give birth to furred and blind cubs in an underground den near the river shore and fishing sites. [63] Pups are more vulnerable, and may be taken by caiman and other large predators,[50] although adults are constantly mindful of stray young, and will harass and fight off possible predators. The hearing of this species is intense and its sense of smell is excellent. Incorrect descriptions of the species have led to multiple synonyms (the latter subspecies is often P. b. paranensis in the literature). It lives only in the rivers and creeks of the Amazon, Orinoco, and La Plata river systems. These otters are able to swim 330 feet (100 meters) in less than 30 seconds. Among the Achuar people, they are known as wankanim,[7] and among the Sanumá as hadami. [50] Other causes of death include accidents, gastroenteritis, infanticide, and epileptic seizures. [4] At Tierpark Hagenbeck in Germany, long-term pair bonding and individualized mate selection were seen, with copulation most frequently taking place in water. © Magic Bones/Getty Giant ottters are very sociable animals and often live in groups of up to 20 individuals. Giant otters in the wild live 10 to 13 years. The giant otter is a large semi-aquatic mammal that lives in the Amazon River basin and in the Pantanal wetlands in South America. Each animal may eat six to nine pounds of food per day. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to 1.7 metres (5.6 ft). 2020 National Geographic Partners, LLC. Size. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. The giant otter shows a variety of adaptations suitable to an amphibious lifestyle, including exceptionally dense fur, a wing-like tail, and webbed feet. [20][21] Early reports of skins and living animals suggested exceptionally large males of up to 2.4 m (7.9 ft); intensive hunting likely reduced the occurrence of such massive specimens. Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. Male giant otters can attain a length of 1.5-1.7m (4.9-5.6ft). [28], 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. Schoolchildren, however, had a more positive impression of the animal. Poaching has long been a problem. 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. 38 chromosomes.
