Cook Inlet belugas eat mostly hooligan or candlefish in the spring and switch to eating mostly salmon in the summer months. They also enjoy eating squid, shrimp, flounder, octopus, clams, mussels, snails, sandworms, pollock and ling cod. They have 32 – 40 teeth but swallow their food whole. They hunt in the shallow water near the coasts allowing for great viewing opportunities by local whale watchers and tourists alike.
Average adults belugas are 12-14 feet long and weight about 3,000 pounds. They have blunt noses, stout bodies with a bump on top of their head. They are slow swimmers and move at about 5 MPH most of the time reaching top speeds of 11 MPH. They live in groups anywhere from 5 to a hundred.

They make whistling sounds that are like the song of a bird. They whistle through their blowhole while underwater but the sounds are loud enough to be heard above the water.
