The Sperm Whale, Physeter macrocephalus, is easily recognized by its massive head and prominent rounded forehead—it also has the largest brain of any living creature known. Its head holds a substance called ‘spermaceti’ which early scientists believed were sperms, but the actual function of the semi-liquid substance is yet unknown. It is the largest of the toothed whales and the largest toothed predator— and has between 18 to 26 teeth on each side of its lower jaw, which fit into sockets in the upper jaw.
