- In December 2008, researchers from the Marine Mammal Institute at Oregon State University completed a DNA tree of 13 of 15 known species of " Mesoplodon " beaked whales ( excluding spade-toothed whale which is only known from a skeletal and a few stranded specimens ).
- To understand the hunting and foraging behavior of beaked whales, researchers used sound and orientation recording devices ( DTAGs ) on two species : Cuvier's beaked whale ( " Ziphius cavirostris " ) and Blainville's beaked whale ( " Mesoplodon densirostris " ).

- In Perrin's beaked whale, the teeth are located near the tip of the lower jaw and are roughly equilateral triangles when viewed laterally and still placed in the jaw; in this they resemble the foreteeth of Baird's beaked whale more than those of the " Mesoplodon " species which are otherwise similar . ( Dalebout " et al . " 2002)

" Berardius " species and Longman's beaked whales ( " Indopacetus pacificus " ) are found in larger groups of up to 100 individuals.
