Habitat: Wetlands, lakes, rivers, and streams; also found in suitable costal regions, where fresh water is available (Kruuk 2006)

Behavior/ Social Structure: Can live in groups/families up to eight individuals but hunt individually (Kruuk 2006)

Communication: Communicate through toilet sites and scent marking through urine, rolling, scraping, and rubbing.  Also communicate through vocalizations such as whistles, huffs, growls and screams. (Kruuk 2006)

Diet:  Mostly crabs, fish (mostly bottom feeders) and mollusks.  Use long clawless toes to forage for food in substrate (Kruuk 2006).

Reproduction: Breeding occurs throughout the year with a gestation of 63 days.  They do not have delayed implantation. Produce 1-3 cubs per year and the young will leave the mother after one year (Kruuk 2006)

Predators: Crocodiles, fish eagles and humans (Lariviere 2001).

Conservation Status: Have been hunted for fur and are losing habitat due to destruction.  However, some research shows they may actually benefit from human encroachment because eutropication of waterways lead to an increase in crabs, their primary food source (Kruuk 2006). Listed as CITES Appendix II, though the population in some areas is listed as Appendix I (ICUN 2011).
