This mysterious animal is so elusive that many in Sri Lanka don’t even know that this mammal occurs in the country. Its short feet webbed in adaptation for aquatic hunting makes it a deadly predator in the waters. Known to raid ponds and wipe out fish in home gardens.  It takes on a chocolate brown color on its sausage like body which ends with a thick based tail. Lives in unpolluted water bodies across the island. Largely nocturnal but is known to swim in lakes around Hunas Falls during the day time. Their diet mainly consists of fish but will also prey on aquatic animals and water birds if the opportunity arises.
