We could not figure out the what type of sea mammal it is.
Observation: Several weeks ago, my nephew David Frankson, photographed a sea mammal on the Chukchi Sea outside of Kivalina, Alaska but we could not figure out what type it was. It has not moored on the beach yet. It may have gone with the tide.

Gay Sheffield, MAP agent writes, "Great that your observer took such a good photos! This is a beluga whale. Through the calm water, you can see the white-colored body and a good outline of the bulbous forehead. Hope that helps." -Gay
LEO says:
It is hard to tell the scale. We wonder if this is perhaps a beluga whale (Delphinapterus leucas). The animal seems to be turned over (belly-up). Strandings can be reported to the Alaska Marine Mammal Stranding Network. The hotline number at NMFS statewide 24-hour Stranding Hotline: (877) 9AK-RPRD or (877) 925-7773. Online Notification Form. The Alaska Veterinary Pathology Services (A.V.P.S.) have been notified of this observation, and Marine Mammal Strandings, Alaska Regional Office, NOAA Fisheries. M. Tcheripanoff
