Bolivia; Brazil; Colombia; Ecuador; French Guiana; Guyana; Paraguay; Peru; Suriname; Venezuela, Bolivia.
The agile and graceful tumbling Olympians of the Amazonian rivers, Giant Otters are able to swim 100 metres in less than 30 seconds. They are also known as the Lobo de Rio (the River wolf), Los Lobos del Rio (Wolves of the River) and Ariranha. They are most active in the mornings and evenings and take a siesta during the hottest parts of the day.

They are endemic to South America, with populations distributed east of the Andes in the Orinoco, Amazonas, and Parana basins, and the hydrographic networks of the Guianas. The northern limit of the Giant Otter’s distribution occurs in northern Venezuela, and the southern limit in Misiones, Argentina.
Threats are predominantly related to the river otter being pushed out of their ecosystems by anthropogenic pressures.
The destruction of the river otters’ riparian habitat, overfishing, contamination of aquatic ecosystems (especially for gold mining, fossil fuel exploration, and the use of pesticides and fertilizers for monocultures), domestic animal diseases, and mismanaged tourism It seems likely that mining activities and the widespread conversion of forest into agricultural and pasture lands will continue unabated in the near future as part of the economic development of the Amazonian countries.
Giant otters highly social animals that are active during the day and evening. They are gregarious and live in groups of 2-20 individuals. A family has a home range of 12 sq. km. They are cooperative and peaceful together and often groom, rest and hunt together and cooperatively construct burrows and establish territories using scent markings from their anal glands to delineate territories.
They communicate through a noisy series of hums, coos, barks and whistles. Newborn pups squeak to elicit attention, while older young whine as they participate in group activities. When intruders invade their territory, the parents and other adults in communities will defend the offspring against danger.
