Today, accidental trappings in beaver traps constitute the most otter fatalities. Joe Jack caught what could be the state's first legally trapped river otter on Nov. 2. [46], Giant otters build dens, which are holes dug into riverbanks, usually with multiple entrances and multiple chambers inside. While young otters swim naturally, the mother must coax them into the water for their first swim. The river otter is protected and insulated by a thick, water-repellent coat of fur. Otters have five toes and the heel pad tends to be somewhat horseshoe shaped.

Giant Otter This South American otter is the world's largest, at some 6 feet long. The North American river otter is found throughout North America, inhabiting inland waterways and coastal areas in Canada, the Pacific Northwest, the Atlantic states, and the Gulf of Mexico. They have been virtually eliminated through many parts of their range, especially around heavily populated areas in the midwestern and eastern United States. New at the Zoo: Meet Our Bushbaby Brothers. [70], The species has also appeared in the folklore of the region. [23], Like other otters, the North American river otter lives in a holt, or den, constructed in the burrows of other animals, or in natural hollows, such as under a log or in river banks. Their long, agile bodies enable them to quickly twist , turn, roll and dive, and they are frequently seen sliding or burrowing in the mud or snow. For example, stress to the parents during cub-rearing due to inappropriate enclosure conditions has been the primary reason for cub neglect, abuse and infanticide. The Maine Fish and Game Commissioner at the time, George J. Stoble, said that the critter, which Bolstridge trapped on the Fish River, was a world's record otter. River otters will eat just about any living creature they can catch. We are thrilled that they are back, he told CNN. Prey chase is rapid and tumultuous, with lunges and twists through the shallows and few missed targets. [49] However, large populations never occurred in areas of Southern California such as the chaparral and oak woodlands and Mojave Desert seasonal waterway regions, or in the xeric shrubland regions in New Mexico, Texas, Nevada, and Colorado. [2] It has no serious natural predators other than humans, although it must compete with other predators, such as the Neotropical otter, jaguar, and various crocodilian species, for food resources. Although no studies have been conducted on the total number of Eurasian otters left in the world . Hartig said that in 2019, river otters were observed in Lake Erie National Park, having swum across Lake Erie. Learn more. A restoration program in western New York has in. In addition, riverine habitats in interior regions supported smaller, but practical, otter populations. Meaning: Lontra is the genus name of American otters, and weiri honors guitarist Bob Weir. [19] Giant otter fossil remains have been recovered from a cave in the Brazilian Mato Grosso. [63] 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. [15] P. b. paraguensis is supposedly smaller and more gregarious, with different dentition and skull morphology. Protect local waterways by using fewer pesticides when caring for your garden or lawn. [11], In a new classification, the species is called Lontra canadensis, where the genus Lontra includes all the New World river otters. About the Smithsonian Conservation Biology Institute, Your Go-to Guide for a Winter Day at the Zoo, What's New at the Smithsonians National Zoo This Summer.

The North American river otter ( Lontra canadensis), also called the Canadian otter, is the most abundant species of otter. [26][34][36][50] Otters consume more aquatic insects in the summer as the populations increase and specific life stages heighten their susceptibility. )[78] 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. [85][86] Bolivia designated wetlands larger than the size of Switzerland as a freshwater protected area in 2001; these are also home to the giant otter.

The otters typically capture prey in their mouths but occasionally use their thumbs and forepaws to grasp and manipulate prey. [25], Giant otter muzzles are short and sloping and give the head a ball-shaped appearance. [5] At Tierpark Hagenbeck in Germany, long-term pair bonding and individualized mate selection were seen, with copulation most frequently taking place in water. The North American river otter used to be abundant throughout New York State, but its numbers have declined. Otters did not make extensive long-distance movements away from the Murphree area. Both otters have their own adorable way of caring for their young and making them feel at home, too. [2], North American river otters, like most predators, prey upon the most readily accessible species. North Andover, MA (01845) Today. Quick hah barks or explosive snorts suggest immediate interest and possible danger. [47] In Canada, North American river otters occupy all provinces and territories, except until recently Prince Edward Island. While many states experienced declines in river otter densities, distribution, and in some cases extirpation in the mid 1800's - 1900's, Georgia's Appearance: Dark shiny brown fur. In the United States, there are sea otters and the North American river otter, or . [16] Each otter pup weighs approximately five ounces. [33] Concern over this endangered species has since generated a body of research. It is regulated internationally under Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) meaning commercial trade in specimens (including parts and derivatives) is prohibited. When threatened or frightened, they emit a hair-raising scream that can be heard up to 1.5 miles (2.4 kilometers) across the water. [22][23] Early reports of skins and living animals suggested exceptionally large males of up to 2.4m (7ft 10+12in); intensive hunting likely reduced the occurrence of such massive specimens. What is clear is that there is a delayed implantation of nine to 11 months, with actual gestation taking about 60 days. North American river otters also currently inhabit coastal regions throughout the United States and Canada. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land.

[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. North American river otters are very susceptible to the effects of environmental pollution, which is a likely factor in the continued decline of their numbers. [10], The North American river otter has long whiskers that are used to detect prey in dark waters. [89] 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. ), and the maximum movement recorded was 7.3 km (4.5 mi.). Acid drainage from coal mines is a persistent water quality issue in some areas, as it eliminates otter prey. [27] Its velvety feel makes the animal highly sought after by fur traders and has contributed to its decline. But the otters return is a beacon of hope for conservationists and environmentalists alike. [52], Studies of giant otters in captivity have given indications about the environment necessary to both maintain a physically and behaviorally healthy population and allow successful cub-rearing. [49] Females have a gestation period of 65 to 70 days, giving birth to one to five pups, with an average of two. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. Therefore, fish are more vulnerable to being preyed upon by otters because the crayfish have become more difficult to obtain. This otter is slightly paler ventrally, especially on the throat. River otters are found throughout most of North America from the Rio Grande to Canada and Alaska, except for in arid deserts and the treeless Arctic. It is at home in streams, rivers, ponds and lakes and is well-adapted for its aquatic lifestyle. River otter populations have declined since the 1600s for numerous reasons, including the fur trade and loss of habitat. The river otter Lontra canadensis is an elusive species that can serve an important role in aquatic ecosystems as a top predator of fish and crayfish. [30][31] Mammals preyed upon by North American river otters are characteristically small or are a type species found in riparian zones. Now more than ever, we need your support.

The animal is susceptible to a variety of diseases, including canine parvovirus. Limits on the number of tourists at any one time, fishing prohibitions, and a minimum safe distance of 50 metres (164ft) are proposed to offer further protection. 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. [14][76][77], 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). [28] This availability is influenced by the following factors: detectability and mobility of the prey, habitat availability for the various prey species, environmental factors, such as water depth and temperature, and seasonal changes in prey supply and distribution in correspondence with otter foraging habitat. Whistles may be used as advance warning of nonhostile intent between groups, although evidence is limited. [50] The few occurrences of mammals found in the North American river otter's diet include remains of the muskrat (Ondatra zibethicus); meadow vole (Microtus pennsylvanicus); eastern cottontail (Sylvilagus floridanus); and snowshoe hare (Lepus americanus). [73], 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. [51], Adult North American river otters are capable of consuming 1 to 1.5 kilograms (2.2 to 3.3lb) of fish per day. [16], North American river otters only settle in areas that consist of vegetation, rock piles, and sufficient coverage. Watch our Sea Otter Cam and see animated sea otters live now on exhibit as they swim, play with toys, lounge in ice buckets and eat during our daily feeding shows at the Monterey Bay Aquarium. bobcats, alligators, coyotes, and raptors are among the large predators that prey on river otters. Otters primarily feed on fish and aquatic organisms including crayfish, frogs, and other miscellaneous animals.

[40] 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. Organize or attend a stream, river, lake or other waterway cleanup in your area to preserve aquatic habitats for local species. If you have seen the elusive river otter in the wild, you are one of the lucky few.At zoos, otters are among the most visited .

[41], Delayed implantation distinguishes the species from the Eurasian otter, which does not do this. And new research on the patterns of the hunting trade has revealed how the giant otter's biology, including its monogamous tendencies and boisterous social lifestyle, may have undermined its. Provided it survives its first year of life, a typical North American river otter will live to the age of 12, with some surviving longer. However, waterpollution, uncontrolled trapping and severe habitat loss have reduced the number of river otters. Their playful snow and mud sliding, tail chasing, water play, and snow burrowing activities also serve other purposesthey help strengthen social bonds and let young otters practice hunting techniques. [63] It occurs in freshwater rivers and streams, which generally flood seasonally.

Utreras[65] presumed habitat requirements and availability would differ dramatically in the rainy season: estimating range sizes of 1.98 to as much as 19.55square kilometres (0.76 to 7.55sqmiles) for the groups. [2] Given local extinctions, the species' range has become discontinuous. SmithsoniansNationalZoo& ConservationBiologyInstitute To him, that's just more evidence of . He grabbed his camera and then got a video of the otters head bobbing out of the water. To protect fish in these cases, the otters may need to be removed or relocated. [48] Study of captive specimens has found only males initiate copulation. ). Since 1976, over 4,000 otters have been reintroduced in 21 U.S. states. Its pretty crazy to be lucky enough to see one.. [35] An analysis published in 2014 cataloged 22 distinct types of vocalization in adults and 11 in neonates. The male otter is generally chased away until the young are weaned and old enough to leave the riverbank, at which time they may return and help raise the pups. The median life expectancy for this species in captivity is 11.7 years, and the longevity record is 21.64 years (Hamilton 2016). The muzzle appears broad. River otter fur ranges from light to dark, rich brown. [36], North American river otters may prefer to feed on crustaceans, especially crayfish (Cambarus, Pacifasticus, and others) and crabs[23] more than fish where they are locally and seasonally plentiful. [74], The animal faces a variety of critical threats. The giant otter or giant river otter[4] (Pteronura brasiliensis) is a South American carnivorous mammal. [84] (One researcher has suggested the giant otter is hunted only in desperation due to its horrible taste. The first beavers to live wild in England for centuries are to be allowed to remain in their new home on the River Otter in east Devon after a five-year reintroduction trial. Otter pups aren't born with swimming skills, they learn from their mothers. [61] 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. [26][32][33] Game fish, such as trout (Salmonidae) and pike (Esocidae), are not a significant component of their diets. [67], Research generally takes place in the dry season and an understanding of the species' overall habitat use remains partial. Theyremain as a family unit for seven to eight months or until the birth of a new litter.
