world record river otter

Lutra was the early European name (from Latin), and the specific epithet canadensis[9] means "of Canada". Females appear to give birth year round, although in the wild, births may peak during the dry season. Populations of river otters in the Delta had been greatly reduced by trapping, pollution and habitat destruction, but in recent years, their numbers have been increasing, and they've expanded. [31][33], Mammals are rarely consumed by North American river otters, and are not a major dietary component. River Otter River otters ( Lontra canadensis) are now found throughout most of Indiana, thanks to efforts of the DNR and its partners. [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. [32][50] Susceptibility of these species is greatest during the summer (when waterfowl broods are vulnerable) and autumn. After a few bumps, they can slide up to 22 feet on the ice. [20] About one-third of the animal's total length consists of a long, tapered tail. In the winter, otters have found the easiest and perhaps most fun way to get around is by sliding. Reintroduction projects have expanded their distribution in recent years, especially in the Midwestern United States. 3.4K subscribers in the DeathObituaries community. Otters did not show strong preference for individual habitat components within their home range. [41], Delayed implantation distinguishes the species from the Eurasian otter, which does not do this. There was so much oil in the river that not only river otters but beavers could not live there. [48] 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. SmithsoniansNationalZoo& ConservationBiologyInstitute [36] A study conducted on captive otters revealed they preferred larger fish, ranging from 15 to 17 centimeters (5.9 to 6.7in), more than smaller fish, ranging from 8 to 10 centimeters (3.1 to 3.9in), and they had difficulty catching fish species less than 10 centimeters (3.9in) or larger than 17 centimeters (6.7in). In Mexico, the North American river otters lived in the Rio Grande and Colorado River Deltas. 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. In the United States, there are sea otters and the North American river otter, or . (Photo by David Cannon/Getty Images). Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. Sea otters weigh more around 45-90 pounds with large, furry faces. Like other carnivores, their teeth are well adapted for grinding and crushing. Robin ( 1987) reported that in 1985, 50% of Eurasian otters were captive born and in 2015 approximately 77% were captive born (Rey . [61] Carter and Rosas have found captive adult animals consume around 10% of their body weight dailyabout 3 kilograms (7lb), in keeping with findings in the wild. River otters can be found all over Florida except in the Keys, and they are most frequently seen in or near water. The entire group, including nonreproductive adults, which are usually older siblings to that year's pups, collaborates to catch enough fish for the young. Prior to the arrival of the next litter, the North American river otter yearlings venture out in search of their own home ranges.[44]. [83] 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. This otter is slightly paler ventrally, especially on the throat. Group hierarchies are not rigid and the animals easily share roles. One report suggests maximum areas 28m (92ft) long and 15m (49ft) wide, well-marked by scent glands, urine, and feces to signal territory. 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. Despite its common name, the North American river otter is equally comfortable in either coastal marine or freshwater habitats. [20], The mothers raise their young without aid from adult males. [29] For instance, Catostomidae are the primary dietary component of North American river otters in Colorado's Upper Colorado River Basin. [84] (One researcher has suggested the giant otter is hunted only in desperation due to its horrible taste. 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 1.08sqmi). Male North American river otters do not seem to be territorial, and newly dispersing males may join established male groups. Otters prefer water bordered by woods and with wetlands, such as marshes, nearby. [28] Unique markings of white or cream fur color the throat and under the chin, allow individuals to be identified from birth. Your effort and contribution in providing this feedback is much Today, accidental trappings in beaver traps constitute the most otter fatalities. Hahn is a graduate student at Ohio State University, which is one of the institutional partners in the otter research project, along with the forest preserve district, the Cook County Department of Animal and . A number of reintroduction projects have been initiated to help halt the reduction in the overall population. Usually when I see something like that, its a muskrat or a mink, which are much more common in this area., How otters and beavers returned to one of the world's greatest golf courses. [75] While still present in a number of north-central countries, giant otter populations are under considerable stress. [28] 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. Little effort has gone into assessing the threat of disease to wild North American river otter populations, so it is poorly understood and documented. They give birth within these dens during the dry season. We look for things like river otters, he said. [8], The Boror 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. These include mudminnows (Umbra limi) and sculpins (Cottus spp.). 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. [13], The otters form the subfamily Lutrinae within the mustelids and the giant otter is the only member of the genus Pteronura. The survival of the giant otter populations in the Guianas is essential to the survival of this endangered species in South America. [2] Given local extinctions, the species' range has become discontinuous. Where the paths hug the river banks you can watch the birdlife and find evidence of animal activity. Water pollution and other diminution of aquatic and wetland habitats may limit distribution and pose long-term threats if the enforcement of water quality standards is not upheld. River otter poop also contains lots of DNA, from what the otters have eaten and from the otters themselves. [32] The North American river otters have also been known to catch and consume moulting American wigeon (Mareca americana) and green-winged teal (Anas crecca). We thought were next, Detroit River is next, he said. Their small heads widen to long necks and shoulders, and they have flattened, well-muscled tails. Appearance: Dark shiny brown fur. North Andover, MA (01845) Today. The North American river otters may leave the den by eight weeks and are capable of sustaining themselves upon the arrival of fall, but they usually stay with their families, which sometimes include the father, until the following spring. However, improvements in water quality (through enactment of clean water regulations) and furbearer management techniques have permitted river otters to regain portions of their range in many areas. North American river otters are natural swimmers and, with parental supervision, they acquire the skills necessary to swim. Other researchers suggest approximately 7 square kilometres (2.7sqmi) 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. [62], The species is amphibious, although primarily terrestrial. Jan. 20, 2022 5:24 PM PT. Free or royalty-free photos and images. The giant otter is diurnal, being active exclusively during daylight hours. [41] One tentative theory for the development of sociality in mustelids is that locally abundant but unpredictably dispersed prey causes groups to form. [63], Local people sometimes take pups for the exotic pet trade or as pets for themselves, but the animal rapidly grows to become unmanageable. In Canto State Park, otters dig their reproductive dens on the shores of oxbow lakes starting around July, when waters are already quite low. Otters are most often confused with mink that live on land and muskrats that live in water. 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. [16] Each otter pup weighs approximately five ounces. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to 1.8m (5ft 11in). 10-30 lbs. [53] However, when water levels are lower, crayfish will seek out shelter while fish become more highly concentrated and susceptible to predation. They prefer unpolluted water with a minimal human disturbance. [34] However, many other studies did not report any findings of North American beaver remains in the scat sampled. Information about river otter breeding and reproductive and social behavior is varied due to the difficulty of studying these animals in the wild. [78] Specific threats from human industry include unsustainable mahogany logging in parts of the giant otter range,[75] and concentrations of mercury in its diet of fish, a byproduct of gold mining. Carnivore. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[5]. [25], Giant otter muzzles are short and sloping and give the head a ball-shaped appearance. [26], Male North American river otters disperse from such family groups more often than females. Typically, otters in northern regions are larger than otters in southern regions, and males are usually larger than females. [11], In a new classification, the species is called Lontra canadensis, where the genus Lontra includes all the New World river otters. 2023 Cable News Network. [50] Likewise, the common carp (Cyprinus carpio) is a preferred fish species for the North American river otter in other regions of Colorado. When the pups are about two months old and their coats grow in, their mother introduces them to the water. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [45] In 2010, the Colorado Department of Wildlife reported the species, reintroduced in the 1980s, was "thriving" and recommended its protection status be reconsidered. Giant otters served as Yaku runa's canoes. The giant otter has a handful of other names. North American river otters rely upon play to learn survival skills such as fighting and hunting. Learn more. The river otter is a remarkable animal to watch on the move, either in the water or on the shore. It is encouraging to note that with these conservation programs, regulations on trappingand the improvement of water quality, the river otters are finally making a comeback in certain wetland areas. A Warner Bros. Both otters have their own adorable way of caring for their young and making them feel at home, too. Scent marking is done by either urinating/defecating or by emitting a strong, musky odor from the paired scent glands near the base of thetail. [13] Fossils of a giant river otter dating back 3.5 Mya (during the Pliocene)[14] have been found in the US Midwest; however, fossils of the modern river otter did not appear in North America until about 1.9Mya. [15][16] The New World river otters originated from the Old World river otters following a migration across the Bering Land Bridge, which existed off and on between 1.8million and 10,000 years ago.

River otters exhibit a variety of vocalizations, ranging from whistles andbuzzes to twitters, staccato chuckles, chirps and growls. Winds E at 5 to 10 mph.. Tonight 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. Also, North American river otters have large molars used for crushing hard objects, such as the shells of molluscs. River otters are adapted to a semi-aquatic lifestyle and can typically be seen "playing" in a stream, river, or alongside the banks of a waterway. Otter births occur most frequently in March or April. That home range shrinks drastically during breeding and rearing season. Life has been unfair to the giant river otter. But cleanup efforts in the past few decades have paved the way for the otters return to the river. In 2004, Peru created one of the largest conservation areas in the world, Alto Purs National Park, with an area similar in size to Belgium. 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. The muzzle appears broad. The otter is a swift and agile swimmer, using its muscular tail to make sharp turns and steering with its neck and webbed feet. Whale watching is . In many places, the populations have re-established themselves because of conservation initiatives. To protect fish in these cases, the otters may need to be removed or relocated. 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. Otters are the largest species of the weasel family measuring in at 3-4 feet long with a 12-18 inch tail. Chasing is also a common game. [38][40], When left unchecked, though, otters can be significant predators under certain circumstances (e.g. It is at home in streams, rivers, ponds and lakes and is well-adapted for its aquatic lifestyle. [1] P. b. brasiliensis is distributed across the north of the giant otter range, including the Orinoco, Amazon, and Guianas river systems; to the south, P. b. paraguensis has been suggested in Paraguay, Uruguay, southern Brazil, and northern Argentina,[14] although it may be extinct in the last three of these four. The otters and their environment still face challenges, including climate change, urban runoff, and the continued legacy of the industrial revolution in the form of contaminated sediments in these rivers and harbors, Hartig said. 2. Some studies indicate that river otters pair for only a few months during the breeding season and have no further strong bonds. River otters are also valued as a game species and furbearer ( Melquist et al. [34][36][54], Records of North American otters preying upon North American beavers (Castor canadensis) vary; it has been reported in the southern boreal forest of Manitoba. These analyses suggest they diverged in the Miocene epoch 23.03 to 5.33million years ago (Mya), which is "much earlier" than indicated in the fossil record. [62] The spectacled caiman is another potential competitor, but Duplaix found no conflict with the species in Suriname. [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. However, waterpollution, uncontrolled trapping and severe habitat loss have reduced the number of river otters. [30][32] They are less likely to be prey for the North American river otters since they are fast-swimming and can find good escape cover. It lives only in the rivers and creeks of the Amazon, Orinoco, and La Plata river systems. The most severe population declines occurred in interior regions where fewer aquatic habitats supported fewer otter populations. Otter species can be found across Eurasia, Africa, India, Japan, Indonesia, North America, South America, and Central America. Two river dolphins, the tucuxi and boto, might potentially compete with the giant otter, but different spatial use and dietary preferences suggest minimal overlap. and over 3 feet long, are found across North America, although their range has been significantly damaged by hunting and habitat. Staff and visitors at the Toronto Zoo are mourning the death of an otter who had recently become ill. They spend a significant portion of the day scent marking territory by urinating, defecating, scratching and rubbing their scent glands on rocks and trees. 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. Moreover, a western Oregon study revealed fish remains were present in 80% of the 103 digestive tracts examined. An adult North American river otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. Giant otters adopt communal latrines beside campsites, and dig dens with a handful of entrances, typically under root systems or fallen trees. 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. [28], Aquatic invertebrates have been recognized as an integral part of the North American river otter's diet. 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. A river otter is a member of the weasel family that enjoys water. The species was listed as endangered in 1999 and wild population estimates are typically below 5,000. Washington, DC 20008. [18] (The North American river otter (Lontra canadensis) is the fourth Lontra member.) Members are our strongest champions of animal conservation and wildlife research. [10] The North American river otter was first classified in the genus Lutra. [2], North American river otters, like most predators, prey upon the most readily accessible species. When you become a member, you also receive exclusive benefits, like special opportunities to meet animals, discounts at Zoo stores and more. and over 3 feet long, are found across North America, although their range has been significantly damaged by hunting and habitat loss. [8], The North American river otter was first described by German naturalist Johann Christian Daniel von Schreber in 1777. North American river otters, also called Canadian otters, have long, muscular, streamlined bodies with short legs and fully webbed feet bearing non-retractable claws. The North American river otter (Lontra canadensis), also known as the northern river otter and river otter, is a semiaquatic mammal that only lives on the North American continent, along its waterways and coasts. Young are born between April andMay and arrivesilky black, blind, toothless and totally helpless. North American river otters get their boundless energy from their very high metabolism, which also requires that they eat a great deal during the day. [25] The fur is extremely dense, so much so that water cannot penetrate to the skin. The animal's well-muscled tail can add a further 70cm (28in) to the total body length. Unlike most otter habitats around the world, it is thought that the Pacific north coast still supports a thriving otter population. The species is widely distributed throughout its range. [26][33], Amphibians and reptiles are more obtainable by the North American river otter during the spring and summer as a result of breeding activity, appropriate temperatures, and water supply for the prey. As it dove, it didnt have the flattened tail like a beaver, which leaves otter as the only possibility, he explained. [57] 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 North American river otter is the most abundant otter species, but surprisingly little is known about its lifein the wild. Weights are between 26 and 32kg (57 and 71lb) for males and 22 and 26kg (49 and 57lb) for females. ), shiners (Notropis and Richardsonius spp. [5] They are weaned by nine months and begin hunting successfully soon after. In comparison, river otters can be found in fresh, brackish, or salt water, and can travel overland for . This ancient otter weighed as much as an adult lion. [38] 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. [10][24][25], Most mustelids, including otters, have 36 specialized teeth, including sharp canines and carnassials that inflict lethal bites to prey. The species is territorial, with groups marking their ranges with latrines, gland secretions, and vocalizations. Even in larger bodies of water, river otters may take disproportional advantage of any seasonal concentrations of fish when and where only very limited areas of suitable spawning, low-flow, or over-wintering habitat may exist. Therefore, fish are more vulnerable to being preyed upon by otters because the crayfish have become more difficult to obtain. They live in riparian zones, which are the areas that border stream, rivers, and lakes. [63] It occurs in freshwater rivers and streams, which generally flood seasonally. 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. While current harvest strategies do not pose a threat to maintaining otter populations, harvest may limit expansion of otter populations in some areas. Meaning: Lontra is the genus name of American otters, and weiri honors guitarist Bob Weir. Josh Salmon,. However, North American river otters remain rare or absent in the southwestern United States. [52] A study conducted on North American river otters in a southwestern Arkansas swamp identified a correlation between crayfish consumption, fish consumption, and water levels.
