The Giant otter or Pteronura brasiliensis ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. Its distribution has been greatly reduced and is now discontinuous. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers.

The Giant otter or Pteronura brasiliensis was listed as endangered in 1999 and wild population estimates are typically below 5,000.

The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs.

It constructs extensive campsites close to feeding areas, clearing large amounts of vegetation. The Giant otter subsists almost exclusively on a diet of fish, particularly characins and catfish, but may also eat crabs, turtles, snakes and small caiman.
