Target Species
Sperm Whale (Physeter macrocephalus)
The sperm whale is the largest odontocete cetacean. It is easy to recognize: the head is huge and squarish; the blowhole is set at the front of the head and is off set to left producing a characteristic forward and to the left blow. The skin is very wrinkled, completely opposite to the other cetaceans. Before a deep diving exposes the flukes completely out of the water surface. Worldwide distribution, perhaps only Killer Whales are more widely. They are distributed from the tropics to the ice edges in both hemispheres. Adults males are found often alone and prefer the high latitudes. Females, juveniles and calves stay on temperate waters and create units characterized by long-term stability; groups usually are constituted by 20 to 30 animals.
