A sperm whale may contain as much as 1,900 L (420 imp gal; 500 US gal) of this oil. [3] 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 ...
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 ...
