Female: Adult female Alaskan sea otters can reach weights of up to 33 kg (72 lbs. They prefer prey fish that are generally immobile on river bottoms in clear water. [48], The giant otter is an apex predator, and its population status reflects the overall health of riverine ecosystems. [59] If fish are unavailable, it will also take crabs, snakes, and even small caimans and anacondas. [73], The animal faces a variety of critical threats. This allows artists to copy reference codes for later use, rather than having to renter the values every time. [74] The animal's relatively late sexual maturity and complex social life makes hunting especially disastrous.[14][75][76]. [83] In a report for World Wildlife Fund in 2002, Duplaix was emphatic about the importance of Suriname and the other Guianas:[63] .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}.

And are otters predators? Giant otters adopt communal latrines beside campsites, and dig dens with a handful of entrances, typically under root systems or fallen trees. Its distribution has been greatly reduced and is now discontinuous. We recommend that these ideas are used as inspiration, that ideas are undertaken with appropriate adult supervision, and that each adult uses their own discretion and knowledge of their children to consider the safety and suitability. The implementation of CITES in 1973 finally brought about significant hunting reductions,[14] although demand did not disappear entirely: in the 1980s, pelt prices were as high as US$250 on the European market. [11] The genus name, Pteronura, is derived from the Ancient Greek words (pteron, feather or wing) and (oura, tail),[12] a reference to its distinctive, wing-like tail. Duplaix documented interaction with the Neotropical otter. Young otters remain in the den for a month but grow up quickly. Fish are supplemented by crustaceans, snakes, and other river creatures. [2] Given local extinctions, the species' range has become discontinuous. Old cells hang around as we age, doing damage to the body. Researchers emphasize that even between groups, conflict avoidance is generally adopted. The giant otter is an especially noisy animal, with a complex repertoire of vocalizations. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. The giant otters are excellent predators as they have whiskers that help them detect the vibrations in the river bed to find prey very quickly.
