[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. The giant otter shows a variety of adaptations suitable to an amphibious lifestyle, including exceptionally dense fur, a wing-like tail, and webbed feet. Like most other otter species, giant otters come ashore to give birth. Clawless otter (genus Aonyx) habitats vary greatly among the species and between individuals. Giant otters live in groups up to 10 individuals, with groups comprising a monogamous pair and their offspring from several generations. [45] The giant otter seems to prefer prey fish that are generally immobile on river bottoms in clear water. The original reason for population decline was the otter's soft fur. [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. Logging, hunting, and pup seizure may have led groups to be far more wary of human activity. . It lives in streams, wetlands and slow flowing larger rivers. The constant need for food requires the family to work together. [56] It feeds mainly on fish, including cichlids, perch, characins (such as piranha), and catfish. The giant otter or giant river otter (Pteronura brasiliensis) is a South American carnivorous mammal.

They take a nap at mid-day during really warm weather. [2] In the former, investigation has shown thinly distributed population remnants. [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. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. The neotropical otter is active during twilight and darkness, reducing the likelihood of conflict with the diurnal giant otter. Giant Brazilian Otter populations in Uruguay and Argentina are thought to be extinct. )[38], Group members share roles, structured around the dominant breeding pair. Its distribution has been greatly reduced and is now discontinuous.

Otters are found almost all over the world and in many wet habitats, such freshwater . 5 years and older. Subadults leaving in search of new territory find it impossible to set up family groups. 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. [33] Concern over this endangered species has since generated a body of research. Strolling from their dwelling down to the river, the parents supervise as older siblings play with the youngsters, frolicking in the water and on the banks. Giant Otter This South American otter is the world's largest, at some 6 feet long. [70], The species has also appeared in the folklore of the region.

The range of the Russian or Asian sea otter extends from northern Hokkaido, Japan to the Commander Islands in the western North Pacific. Nearly all otter populations have been impacted to some extent by human activities. Giant otters are strictly carnivorous (piscivorous) and mainly fish such as cichlids, perch, characins (such as piranha), and catfish. Also, there are two known subspecies: P. b. Brasiliensis and P. b. Paraguensis. 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. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. They hunt alone or in groups, sometimes using coordinated efforts, and must be successful often to meet their daily intake quota. The burrow's main entrance may be under water. California otters often prefer kelp beds, probably because of the protection and food resources they provide. They can open their eyes after 1 month and start to regularly follow their parents out of the den. This species was excessively hunted up until the late 1970s for its valuable fur. [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. [2] Given local extinctions, the species' range has become discontinuous. Other water habitats include freshwater springs and permanent freshwater lakes. Each giant otter needs up to nine pounds of fish per day, so with twenty mouths to feed that's quite a lot of hunting! for females. [69] Pups are more vulnerable, and may be taken by caiman and other large predators,[52] although adults are constantly mindful of stray young, and will harass and fight off possible predators. A group of giant otters easily corners and captures fish. [21], The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. It constructs extensive campsites close to feeding areas, clearing large amounts of vegetation. The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. [39] 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. 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. 302 lessons.

[48], The giant otter is an apex predator, and its population status reflects the overall health of riverine ecosystems. It lives only in the rivers and creeks of the Amazon, Orinoco, and La Plata river systems. [59] If fish are unavailable, it will also take crabs, snakes, and even small caimans and anacondas. [62] The spectacled caiman is another potential competitor, but Duplaix found no conflict with the species in Suriname. [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. [39] 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. Photo by: Frank Hajek.

Gymnotids, such as the electric eel, and the large silurid catfish are among aquatic competitors. They live in family groups, composed of 2-15 individuals, including a dominant breeding pair, non-breeding subadults, and offspring. Incorrect descriptions of the species have led to multiple synonyms (the latter subspecies is often P. b. paranensis in the literature). Its webbed feet, semi-flattened tail and . [75] While still present in a number of north-central countries, giant otter populations are under considerable stress. They are considered a keystone species which essentially means that they help maintain biodiversity. [14] Total population numbers are difficult to estimate. Abstract.

[5] At Tierpark Hagenbeck in Germany, long-term pair bonding and individualized mate selection were seen, with copulation most frequently taking place in water. [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. [91] A Maxacali creation story suggests that the practice of otter fishing may have been prevalent in the past.[92]. [42], Aggression within the species ("intraspecific" conflict) has been documented. [55], The longest documented giant otter lifespan in the wild is eight years.

All otters produce vocalizations, but by frequency and volume, the giant otter may be the most vocal. 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. 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 when fish concentrations in the dwindling lakes and channels are at their peak.
