Unlike many other mammal species, otters' range did not contract during 1550-1950 . Follow us on Instagram at @natgeoyourshot or visit us at natgeo.com/yourshot for the latest submissions and news about the community. Logging, hunting, and pup seizure may have led groups to be far more wary of human activity. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. Celebrate A Conservation Success Story During Sea Otter Awareness Week!, Blogger, 2 Oct. 2017, natural-history-journal . tree-bark mulch and soft pebble-free sand/soil). River otters dig their own burrows. In this article, I am going to talk about Giant Otter size, animal, vs sea otter, size . [41] One tentative theory for the development of sociality in mustelids is that locally abundant but unpredictably dispersed prey causes groups to form. Behavior and Diet As humans, we rely heavily on eyesight to get around in the world. When diving, their ears and nose close when they submerge underwater as well. The West Island zoo officially opened a $1.4-million river otter habitat Tuesday, one . 5 How many cubs do giants otters have? Fish are supplemented by crustaceans, snakes, and other river creatures. As the largest otter, it can reach up to 2m in length. [72] Its smaller prey, different denning habits, and different preferred water types also reduce interaction. [20], 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 14million years ago. Most are small, with short ears and noses, elongated bodies, long tails, and soft, dense fur. Though most live in freshwater rivers, lakes, and wetlands, the sea otter and the smaller marine otter are found in the Pacific Ocean. Decades of poachingfor its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. Hunting in shallow water has also been found to be more rewarding, with water depth less than 0.6 metres (2.0ft) having the highest success rate. However, today the giant otter faces different challenges with humans. Reproductive maturity is reached when they are 2 years old. Otters are usually found no more than a few hundred meters from water. The giant otter is the South American cousin to the sea and river otters of North America, as well as those of Europe and Africa. Habitat fragmentation and loss, as well as pollution, are the current major threats to the Giant otter, as the areas where they live are degraded and destroyed by logging, mining, and damming. [79][80], Other threats to the giant otter include conflict with fishermen, who often view the species as a nuisance (see below). [16] Biologist Nicole Duplaix calls the division of "doubtful value". 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. How U.S. abortion laws went from nonexistent to acrimonious, These Native Americans were taken from their families as children. 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 giant otter is almost 1.5 m long, with an additional metre provided by its tail. The giant otter is found in South America in a range of countries including Peru, Venezuela and Brazil. [13] Later gene sequencing research on the mustelids, from 2004, places the divergence of the giant otter somewhat later, between five and 11million years ago; the corresponding phylogenetic tree locates the Lontra divergence first among otter genera, and Pteronura second, although divergence ranges overlap. A giant mass of seaweed threatens beach season in the U.S. What is aquaculture? Nearly all otter populations have been impacted to some extent by human activities. Otters play a significant role in their representative habitats, which include giant kelp forests and rocky shorelines. There may be fewer than 1,000 marine otters left throughout their range. [48] Study of captive specimens has found only males initiate copulation. Its webbed feet, semi-flattened tail and . SOUTH YORKSHIRE, England - A wildlife park in England is celebrating the surprise arrival of rare giant otter triplets. 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. 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. The new arrivals were born on March 27 and are still under the care of doctors. [67], Research generally takes place in the dry season and an understanding of the species' overall habitat use remains partial. They have thick fur that caused them to be hunted to near extinction. Support the River otters. Giant Otter habitat, underwater viewing gallery & waterfall | City Zoo | Planet Zoo | Speed build | Aquatic Pack | Speedbuild | Enclosure | Exhibit | Speedbuild | King Penguin | Grey Seal |. Illegal killing still occurs, often at the hands of fishermen, who see Giant otters as competition for fish. They chase prey rapidly and tumultuously, with lunges and twists through the shallows and few missed targets. The Civil War raged outside their homes. A giant mass of seaweed threatens beach season in the U.S. What is aquaculture? Who buys lion bones? The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. The International Union for Conservation of Nature (IUCN) considers the species' presence in Argentina and Uruguay uncertain. Giant otters prefer habitats with non-floodable banks that have vegetation cover and where there is easy access to hunting places in relatively shallow waters. Their numbers are currently declining, with no population recovery in sight. They den by burrowing into banks or under fallen logs, and establish a home territory that they will aggressively defend. [52][53][54], 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. Giant otters are able to swim 330 feet (100 meters) in less than 30 seconds. 23 chapters | Like humans, giant otters are quite gregarious. Spraint stations are areas designated by otters for routine, systematic defecation. The IUCN lists Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, and Venezuela as current range countries. 2023 SeaWorld Parks & Entertainment, Inc. All Rights Reserved. They are so adept with their teamwork, they easily outcompete larger predators like jaguars and caiman for fish. Its distribution has been greatly reduced and is now discontinuous. 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. Giant otters are especially noisy and have a complex repertoire of vocalizations. The fact that it is exclusively active during the day further suggests its eyesight should be strong, to aid in hunting and predator avoidance. [62] 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 species was listed as endangered in 1999 and wild population estimates are typically below 5,000. [2] Typically, loggers first move into rainforest, clearing the vegetation along riverbanks. [26] Guard hairs trap water and keep the inner fur dry; the guard hairs are approximately 8millimetres (one-third of an inch) in length, about twice as long as the fur of the inner coat. 52-million-year-old bat skeletons are the oldest ever found. Habitat degradation and loss is the greatest current threat. Please be respectful of copyright. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. Like most other otter species, giant otters come ashore to give birth. Fish make up most of the giant otter's diet. Three giant otter pups were recently born at Yorkshire Wildlife Park (YWP) in the United Kingdom, a big win for the endangered species. The survival of the giant otter populations in the Guianas is essential to the survival of this endangered species in South America. The otters will have 6,000 square feet to play around in their new home. These huge members of the weasel family swim by propelling themselves with their powerful tails and flexing their long bodies. The giant otter is diurnal, being active exclusively during daylight hours. The Civil War raged outside their homes. Sea otters inhabit coastal areas and islands of the eastern and western North Pacific Ocean. We present findings on the demography of a population inhabiting the floodplain of Manu National Park, south-eastern Peru, arising from 14 annual dry season censuses over a 16 year period. Insufficient land area proportions and unsuitable substrate conditions in zoos have historically been the primary cause of high cub mortality and physical and behavioral health problems among giant otters. They also have webbed feet, water-repellent fur to keep them dry and warm, and nostrils and ears that close in the water. [60], The species can hunt singly, in pairs, and in groups, relying on sharp eyesight to locate prey. . Charismatic, vocal, unpredictable, domestic, and playful are all adjectives that aptly . [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. Young are weaned at the age of 3-4 months. [75] The animal's relatively late sexual maturity and complex social life makes hunting especially disastrous. French. We compared giant otter feeding habits between seasons and habitats in the Southern Pantanal, Brazil, by analyzing feces . The giant otter possesses short fur compared to other otter . These beautiful creatures, covered in muscles coated with a dark brown fur are endangered due to habitat destruction and hunting. Create an account to read the full story and get unlimited access to hundreds of Nat Geo articles. Each animal may eat six to nine pounds of food per day. All rights reserved, Do Not Sell or Share My Personal Information. [13] Both species also show strong pair bonding and paternal engagement in rearing cubs. 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. 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. This photo was submitted to Your Shot, our photo community on Instagram. and weighing just 1 to 5 kg (2.2-11 lbs.). Why are these fun loving creatures in such a bad situation? Eurasian otters are found throughout most of Europe, Asia, and North Africa (Morocco, Algeria, and Tunisia). 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. If you've ever gotten a nose full of water in a swimming pool, you understand this is a very valuable adaptation! year-round, peak in late spring-early summer. Contribute to the cause. A wildlife park in the U.K. welcomed a "surprise" litter of otter triplets. Sponsor a River otter. [87], Throughout its range, the giant otter interacts with indigenous groups, who often practice traditional hunting and fishing. They live in monogamous pairs with several generations of family, sometimes with 20 individuals living together. Plants can talk. Rolling places are bare patches of ground where otters roll and groom. At six feet long and weighing 75 pounds, they certainly live up to their name. [48][49] 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. Because of their size and speed of swimming, Giant otters are successful in competing for fish with Black caimans and jaguars. Most otter species have at least one permanent burrow (den) by water. [17] The ears are small and rounded. Twenty-nine groups of giant otters were recorded in an area corresponding to 10% of the total reservoir. A home range is the portion of land and water that an animal frequently visits during its daily and seasonal activities. The giant otter is the longest species in the mustelid family. Since the 1990s, the southwestern stock of Alaskan sea otters has experienced a dramatic (up to 70% population) decline, most likely due to increased predation by killer whales. The giant otter or giant river otter, scientific name Pteronura brasiliensis is a South American carnivorous mammal. They can open their eyes after 1 month and start to regularly follow their parents out of the den. Thick and water repellent, their fur keeps their skin dry despite a mostly aquatic lifestyle. Its distribution has been greatly reduced and is now discontinuous. Full. These animals are most active from 10-11 am and from 3-5 pm. Most otters have widespread distributions, but relatively sparse populations. These can become quite extensive, including "backdoor" exits into forests and swamps, away from the water. [75][82], In 2006, most of this species lived in the Brazilian Amazon and its bordering areas. Congo clawless otters appear to inhabit only small, torrential mountain streams in heavy rainforest areas.

All rights reserved, Do Not Sell or Share My Personal Information. [49] Females have a gestation period of 65 to 70 days, giving birth to one to five pups, with an average of two. Gymnotids, such as the electric eel, and the large silurid catfish are among aquatic competitors. Unfortunately, humans are not quite as skilled at fishing and see giant otters as competition for valuable profits. Gestation lasts 65-70 days and the altricial young are born in late August until early October. [44][45] Within groups, the animals are extremely peaceful and cooperative. [2] Given local extinctions, the species' range has become discontinuous. Reproductive behavior has largely been documented by observations of captive animals. Most seem to prefer quiet ponds and sluggish streams. [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. [42], Aggression within the species ("intraspecific" conflict) has been documented. Although some breeding occurs throughout the year, the peak of the breeding season is from late spring to early summer. 04. [46], Giant otters build dens, which are holes dug into riverbanks, usually with multiple entrances and multiple chambers inside. 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.

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. It then slopes upward to a nest chamber above the high-water level. Learn about the giant river otter's habitat, population, and behavior. A group of giant otters easily corners and captures fish. [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. In Canto State Park, otters dig their reproductive dens on the shores of oxbow lakes starting around July, when waters are already quite low. Plants can talk. 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. [24] [62], The species is amphibious, although primarily terrestrial. Other countries have taken a lead in designating protected areas in South America. It is a gregarious species, living in groups of up to 20 individuals, and will attack potential predators such as caimans. [2] In the former, investigation has shown thinly distributed population remnants. brasiliensis. See how Nat Geo photographed elephants over 100 years, The secret superpowers of elephants, in stop motion. for males and about 7 km (4.3 mi.) Today you'll be learning about the giant otter. Incorrect descriptions of the species have led to multiple synonyms (the latter subspecies is often P. b. paranensis in the literature). Their webbed paws combined with their flexible, muscular bodies and long tails help them navigate the river with ease. 535-640 mm. The tail is well-muscled and can be as long as 28 inches. Habitat degradation and loss is the greatest current threat. Quick hah barks or explosive snorts suggest immediate interest and possible danger. Giant otters Pteronura brasiliensis are semiaquatic mammals that mainly eat fish, the abundance of which is affected by seasonal flooding and habitat structure. The giant otter's hearing is acute and its sense of smell is excellent. The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs. Today we're going to learn more about where they live, how their populations are changing and some cool facts about the giant otter. She is also certified in secondary special education, biology, and physics in Massachusetts. [48][49] They then search for new territory to begin a family of their own. French. California sea otters are found off the coast of central California; between Half Moon Bay and Pt. Axolotls and capybaras are TikTok famousis that a problem? The charismatic otter, a member of the weasel family, is found on every continent except Australia and Antarctica. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to 1.7 metres (5.6ft). Slides offer quick access to water or other facilities. Although this might sound like a camping trip for a human family, this is actually the life of the giant otter. The giant otter (Pteronura brasiliensis) is an endangered semi-aquatic carnivore of South America. [17], 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. Male giant otters can attain a length of 1.5-1.7m (4.9-5.6ft). Although there is somewhat limited data about the exact number of giant otters in the wild, scientists agree that they are an endangered species, in danger of going extinct. How U.S. abortion laws went from nonexistent to acrimonious, These Native Americans were taken from their families as children. A capacity for aggressive behavior should not be overstated with the giant otter.

[5] Other sources have found greater intervals, with as long as 21 to 33 months suggested for otters in the wild. [66] Giant otters may adopt preferred locations perennially, often on high ground. There are estimates for the populations of a few areas: 2,000-5,000 individuals in the Brazilian Pantanal; 180-400 individuals in Madre de Dios, southeastern Peru; 31 individuals in Cantao State Park, Brazil; 75 individuals in Amana, Brazil; at least 130 individuals in Balbina Lake, Brazil; 54 individuals in Araguaia, above Bananal Island; 32 individuals in Yasuni National Park, Ecuador; and at least 35 individuals in Rewa Head, Guyana. Hums and coos are more reassuring within the group. Otters are very social animals, and considerable amounts of time are spent on grooming, playing, and resting together, as well as cooperatively hunting. Home ranges vary in size with species, location, and resource distribution, and are generally larger for males. They give birth within these dens during the dry season. The giant otter subsists almost exclusively on a diet of fish, particularly characins and catfish, but may also eat crabs, turtles, snakes and small caimans. A male's range often overlaps that of one or more females. Quick hah barks or explosive snorts suggest immediate interest and possible danger. There are 1-5 pups in a litter (usually 2-3) and they stay in the family den until they are 2-3 weeks old. [75] While still present in a number of north-central countries, giant otter populations are under considerable stress. [47], Suriname still has significant forest cover and an extensive system of protected areas, much of which protects the giant otter. Despite the fact that it is a hydroelectric lake, the water level can vary annually . It turns out the thick, luscious fur that keeps them dry and warm has been a long coveted possession of humans. These consist of a dominant breeding pair, their offspring from several litters, and sometimes unrelated non-breeding adults. Research article. They inhabit slow moving rivers in forests, swamps and marshes, preferring clear water with gentle sloping banks and over . It may be the solution to overfishing. [63] It occurs in freshwater rivers and streams, which generally flood seasonally. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. Cape clawless otters are found in widely varying habitats, from dense rainforest to open coastal plain and semi-arid zones. Preserve Qubec's wildlife. [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). Statistics show between 1959 and 1969 Amazonian Brazil alone accounted for 1,000 to 3,000 pelts annually. They are seen within the Amazon, Orinoco, and La Plata River systems and are found in slow-moving streams and rivers, lakes, swamps, and marshes, as well as flooded forests during the rainy season. Within groups, otters are extremely peaceful and cooperative. A population of Giant otter was studied in the central Brazilian Amazon at the Xixua Reserve, Roraima (048'S, 6133'W), in order to gather preliminary information on spatial use of habitat. - Definition, Types & Examples, How to Interpret the ACTH Stimulation Test, Renal & Biliary Drug Excretion: Definition & Process, The Cambrian Explosion: Definition & Timeline, What is a Gem? The triplets were born on . [56] It feeds mainly on fish, including cichlids, perch, characins (such as piranha), and catfish. [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. They were hunted nearly to extinction, but conservation measures have allowed some populations to recover. [45] The giant otter seems to prefer prey fish that are generally immobile on river bottoms in clear water. [28] Unique markings of white or cream fur color the throat and under the chin, allow individuals to be identified from birth. The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries. Trees surround them in the tropical forest, providing shade in the heat of the midday sun. Chris Oberholtz. [70], The species has also appeared in the folklore of the region. The species was so thoroughly decimated, the number dropped to just 12 in 1971. Explore their stories. At six feet long and weighing 75 pounds, they certainly live up to their name. Lobo de Rio (the River wolf), Los Lobos del Rio (Wolves of the River), Ariranha, Giant otter, Giant river otter. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[5]. Heres how. The giant otter inhabits almost exclusively the Amazon-Orinoquia river basin , although it has been extremely persecuted and hunted, to the point that its habitat has been significantly reduced. California otters often prefer kelp beds, probably because of the protection and food resources they provide. This species is monogamous, and pairs stay together for life. A wavering scream may be used in bluff charges against intruders, while a low growl is used for aggressive warning. The giant otter shrew ( Potamogale velox ) is a semiaquatic, carnivorous afrotherian mammal. A wavering scream may be used in bluff charges against intruders, while a low growl is used for aggressive warning. Weights are between 26 and 32kg (57 and 71lb) for males and 22 and 26kg (49 and 57lb) for females. Can we do the same? Language links are at the top of the page across from the title. [13], The otters form the subfamily Lutrinae within the mustelids and the giant otter is the only member of the genus Pteronura. Giant otters adopt communal latrines beside campsites, and dig dens with a handful of entrances, typically under root systems or fallen trees. [25] The fur is extremely dense, so much so that water cannot penetrate to the skin. The other two clawless otters are similar in size to river otters. Please be respectful of copyright. All rights reserved. In other otter species, vision is generally normal or slightly myopic, both on land and in water. [36] Each family of otters was shown to have its own unique audio signature. It plays an important role in the mythology of the Achuar people, where giant otters are seen as a form of the tsunki, or water spirits: they are a sort of "water people" who feed on fish. Yes, really. Schoolchildren, however, had a more positive impression of the animal. Giant otters are mammals related to the weasel family. It may be the solution to overfishing. 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. A family has a home range of 12 sq. Giant otters (genus Pteronura) are found mainly in slow-moving rivers and creeks within forests, swamps, and marshes.
