Happy #WorldOtterDay! The L.A. Zoo is home to vivacious giant otters. As you might guess, this is the largest otter species, and individuals may grow up to six feet in length. They live on the banks of streams, lakes, and swamps in the Orinoco, Amazon, and La Plata river systems of South America. Listed as endangered according to the IUCN red list, their main threats are poaching, habitat destruction, and pollution.
