Baird's Beaked Whale

Baird's beaked whale is an exceptionally large toothed whale with a long cylindrical body, small flippers and a prominent forehead above a long beak. Adults of both sexes retain two pairs of visible teeth near the tip of the lower jaw and accumulate pale linear scars. Mature animals reach roughly 10–12m and may weigh about 12 tonnes (Wikipedia, general species account).

This species occupies deep North Pacific waters, often near continental slopes and submarine canyons. It dives for deep-water squid and fish and may remain submerged for an hour or longer. Baird's beaked whales are unusually social for their family, commonly travelling in cohesive groups of several animals and sometimes much larger aggregations. Surfacing is generally slow and deliberate (Wikipedia, general species account).
