East Siberian Sea ("Eschrichtius robustus"), beluga ("Delphinapterus leucas") and narwhal ("Monodon monoceros"). Major fish species are grayling and "Coregonus" (whitefishes), such as muksun ("Coregonus muksun"), broad whitefish ("Coregonus nasus") and omul ("Coregonus autumnalis"). Also common are polar smelt, saffron cod, polar cod, flounder and Arctic char. The coast of the East Siberian Sea was inhabited for ages by the native peoples of northern Siberia such as Yukaghirs and Chukchi (eastern areas). Those tribes were engaged in fishing, hunting and reindeer husbandry, as reindeer sleds were essential for transportation and hunting. They were joined and absorbed by Evens and Evenks around the 2nd century
