The ashy beluga, Delphinapterus fume, is the most common of the four species of beluga in the Neocene. They can be 6 meters long and 2,200 lb in weight. They are also the favored prey of sea bears. Ashy belugas can be distinguished from other species by their higher pitched chirps, clicks, and sqeaks. They also differ in the smoky grey coloration that gives them their name. Ashy belugas mainly hunt squid and other deep sea invertabrates. They can dive to depths of over 100 meters to find their food. Ashy belugas typically live in pods of up to nine individuals. The pods usually hunt together, enhancing the likelyhood of them catching prey.
