with calm water, preferentially inhabiting sites in densely
forested areas. These otters can be found in marine environments
providing they are near a source of fresh water.

The Southern River Otter inhabits southern Chile and western
Argentina, and parts of Peru.

for fur, and pollution. Poaching has significantly decreased
the southern otter's population, and much of its habitat
has been altered for farming.

Behavior
Life
Cycle: Little is known about the life cycle of this species.
It is assumed to be similar to those of related species.
What is known is that they have a very short life span. Few
live to maturity, and only 1% live 10 years of age.
Social:
Southern River Otters are generally solitary, only coming
together to mate. The female raises the pups alone, and there
are no social groups beyond this.
Individual:
This otter is largely nocturnal. They have territories like
other otters, but the size of these territories is unknown.
It appears that they are not particularly defensive of them.
About:
