Beluga whales eat a wide variety of benthic and pelagic prey such as worms, crustaceans, squid, octopus and small fish in shallow and coastal waters although diets vary with season, location, age and body size. Arctic species feed mainly on shallow water fish. An adult beluga will consume approximately 55 lbs (25 kg) of food in a day. Beluga whales can remain submerged for 15-20 minutes and may travel up to 2-3 km on one dive. This allows them to pursue their primary diet of small fish such as capulin, char, sand lance and cod.
