Oriental Small-clawed Otter - Diet and Eating Habits

Diet and Eating Habits

Oriental small-clawed otters feed mainly on invertebrates such as crabs and other crustaceans, molluscs and amphibians. The hindmost upper teeth (pm4 and m3) are broad and robust and are specialized for crushing the exoskeletons of crabs and other hard shelled prey. They also feed on insects and small fish such as gouramis and catfish. They supplement their diet with rodents and snakes. Apart from crabs, the major prey items are mudskippers (Gobioidei). There is much seasonable variability in the diet. They hunt food by using their vibrissae to detect movements of prey in the water. They use their forepaws to locate and capture items rather than their mouths. Their incomplete webbing gives them a great deal of manual dexterity. They dig in sand and mud for shellfish such as clams, mussels and crab. To get at the meat they crush the shell manually or let heat from the sun force the shells to open.
