Sperm whaling is the human practice of hunting sperm whales, the largest toothed whale and the deepest-diving marine mammal species, for the oil, meat and bone that can be extracted from the cetaceans' bodies.

Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
The morphology of the nasal complex is believed to be homologous in all of the echolocating Odontoceti (toothed whales), with the spermaceti organ homologous to the dorsal bursa in the dolphin. [4] The hypertrophied quality of the sperm whale's nose can be interpreted as an adaptation for deep diving unique to Physeteroidea. [5]
