Longman's beaked whales look rather similar to both mesoplodont beaked whales and bottlenose whales, which led to a great deal of taxonomic confusion. The Maldives female had a robust body like the bottlenoses, although this may be a distortion, since the less-decomposed female specimen from Japan had a laterally compressed body typical of Mesoplodon.
Longman's beaked whale (Indopacetus pacificus, also known as the Indo-Pacific beaked whale or the tropical bottlenose whale) was originally assigned to Mesoplodon, but Joseph Curtis Moore placed it in its own genus, Indopacetus, a taxonomic assignment which has been followed by all researchers.
To understand the hunting and foraging behavior of beaked whales, researchers used sound and orientation recording devices on two species: Cuvier's beaked whale (Ziphius cavirostris) and Blainville's beaked whale (Mesoplodon densirostris). These whales hunt by echolocation in deep water (where the majority of their prey is located) between ...

The five-meter-long creature, a type of beaked whale, was identified after it washed ashore on an Otago beach from its color patterns and the shape of its skull, beak and teeth.
According to the DOC, the spade-toothed whale was first documented in 1874 from lower jaw and teeth samples collected on Pitt Island, around 500 miles off New Zealand’s west coast.
For example, the Longman's beaked whale is only known from skulls washed ashore in Somalia and Australia. It has never been seen alive!...in baleen whales females are bigger than males, while in the toothed whales the males are bigger than females....the open mouth of an adult southern right whale can be two metres wide!
