Neotropical otter

The neotropical otter or neotropical river otter (Lontra longicaudis) is an otter species found in Central America, South America and the island of Trinidad.

They are physically similar to the northern and southern river otter, which occur directly north and south of this species' range. The length of the neotropical otter can range from 90–150 centimetres (35–59 in), of which the tail comprises about a third. Body weight ranges from 5–15 kilograms (11–33 lb). Otters are members of the family Mustelidae, the most species-rich (and therefore diverse) family in the order Carnivora.

Since 2008, this otter has been classed as Data Deficient. This otter is found in many different riverine habitats; including deciduous and evergreen forests, savannas, llanos and pantanal. They prefer to live in clear fast-flowing rivers and streams. They are a relatively solitary animal and feed mostly on fish and crustaceans.

Characteristics

The neotropical otter is covered in a short, dark grayish-brown pelage. Fur color is lighter around the muzzle and throat. They possess a long wide tail, with short stout legs and fully webbed toes. Sexually dimorphic, the males are about 25% larger than the females. Body mass of the otter generally ranges from 5 to 15 kilograms. Neotropical otters will communicate with nearby otters via scent marking. Communication may also occur via whistles, hums, and screeches.
