Calves are born in the summer, and mothers nurse their calves for 2 years. Belugas molt each summer. They travel to shallow areas and rub their bodies against the bottom to help remove the old skin.

During molting, skin grows about times faster than normal. Feeding Ecology Belugas are generally considered to be opportunistic feeders.

Fish species make up a large part of their diet including herring, capelin, smelt, cod, salmon, flatfish, sculpin, lingcod, and eulachon. They will also feed on octopus, squid, shrimp, crab, clams, mussels, snails, and sandworms.

Feeding occurs over the continental shelf, in nearshore estuaries, and in river mouths. Most feeding dives are fairly shallow and last 2—5 minutes. However, belugas are capable of diving to depths exceeding feet.

They have been documented to travel under the ice up to miles from open water. Behavior Belugas are social animals and generally travel in small pods.

However, pods of over individuals have been documented. The pods do not seem to have a fixed structure. It is common for individuals to move between pods.

Adult males often travel together, and females with juveniles generally form separate pods. When travelling in pods, belugas frequently surface simultaneously to breathe.From over 50 industries, here are GIS applications to open your mind of our amazing planet, its interconnectivity with location intelligence in mind.
