Berardius bairdii (Baird's Beaked Whale; north Pacific bottle-nosed whale)

Synonyms: Berardius bairdi; Berardius bairdi bairdi; Berardius vegaae; Berardius vegae; Berardius vegana

Wikipedia Abstract

Giant beaked whales are three species of beaked whales in the genus Berardius: Arnoux's beaked whale (Berardius arnuxii) in cold Southern Hemisphere waters, and Baird's beaked whale (Berardius bairdii) in the cold temperate waters of the North Pacific. An as yet unnamed third species was described in 2016. They are the largest of the beaked whales, growing up to 10–12 m in length. They are sometimes referred to as "four-toothed whales" or "giant beaked whales", but are most commonly known by their genus name, Berardius. Arnoux's and Baird's beaked whales are so similar that researchers have debated whether or not they are simply two populations of the same species. However, genetic evidence and their wide geographical separation has led them to be classified as separate.
