Wikipedia Abstract

Blainville's beaked whale (Mesoplodon densirostris), or the dense-beaked whale, is the widest ranging mesoplodont whale and perhaps the most documented. The French zoologist Henri de Blainville first described the species in 1817 from a small piece of jaw — the heaviest bone he had ever come across — which resulted in the name densirostris (Latin for "dense beak").
