Toothed whale whales do not have wax ester deposits nor branched fatty chain acids in their blubber. Thus, more recent evolution of these complex blubber traits occurred after baleen whales and toothed whales split, and only in the toothed whale lineage.

Their skulls have small eye orbits, long beaks (with the exception sperm whales), and eyes placed on the sides of their heads. Toothed whales range in size from the and vaquita to
Toothed seadevil what the toothed seadevil feeds upon and how. It has been suggested that their external jaw teeth serve to entangle soft-bodied invertebrates. The males are fully parasitic, using tooth-bearing denticles at the tips of their jaws to attach to the female and their tissues and blood vessels becoming fused with that of the female. Toothed seadevil The toothed seadevil, spiny seadevil or netbeard seadevil, "(Neoceratias spinifer)", is a rarely seen deep-sea anglerfish found in the mesopelagic and bathypelagic zones of the western central Pacific Ocean. It is the only species in the family Neoceratidae, and is unique amongst the deep-sea
