Giant otter spatial distribution has been related to prey abundance and local habitat conditions (Carter and Rosas, 1997, Davenport, 2010, Rosas-Ribeiro et al., 2012) that are thought to determine core group territory (Carter and Rosas, 1997). The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries.

Hence, otters are closely related to these creatures. he giant otter shows a variety of adaptations suitable to an amphibious lifestyle, including exceptionally dense fur, a wing-like tail, and webbed feet.
