Giant Otter

Giant Otter, Pteronura brasiliensis

While Sea otters can also weigh up to 100 pounds, Giant river otters are definitely the longest members of the weasel family, reaching five-and-a-half feet in length. Found in noisy groups of up to eight, related animals along rivers in tropical South America, they are active only during the day time.

Until recently, it was a very rare animal in zoos, but increasing numbers are being bred in captivity.
