There are no dorsal fins. Thirty-eight spoon shaped teeth are present. Food Habits Belugas eat a wide variety of prey, more diverse than most cetaceans. Many fish species, such as herring, cod, and salmon, as well as invertebrates such as octopus, squid, crab, and snails are taken. In addition, stomachs of belugas have been found to contain bottom-dwelling organisms.
Echolocation is thought to aid in the search for food.
Reproduction One young per birth is the rule for belugas. Calving occurs between April and September. Females give birth every 2-3 years. Gestation lasts about one year and the young are 70 kg. at birth. When born, young are a dark brown or black, reach a blue stage between one and two years, and then have a lighter yellow phase until they reach sexual maturity when the white color typical of this species is achieved.
