Physeter macrocephalus (Sperm Whale)

Synonyms: Physeter australasianus; Physeter australis; Physeter catodon

Wikipedia Abstract

The sperm whale (Physeter macrocephalus), or cachalot, is the largest of the toothed whales and the largest toothed predator. It is the only living member of genus Physeter, and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.Mature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length.

EDGE Analysis

The sperm whale has the largest brain on earth. The head, which also houses the spermaceti organ, occupies about one third of the sperm whale's body. The name sperm whale derives from the oil contained in the spermaceti organ, which early whalers thought looked like semen. In fact the spermaceti organ is used by whales to communicate, which is an important feature of this very sociable animal's life. Sperm whales are found across the globe, avoiding only ice packed oceans. They feed mainly on squid and fish. To catch this prey, sperm whales are able to dive up to 2km deep for 45 minutes at a time. Sperm whales were hunted between the early seventeenth and mid nineteenth century for their oil and this led to a massive decline in population numbers. Today, Japan is the only country which still continues to hunt this species.
