Amazing Creatures: Sperm Whales

The sperm whale or cachalot is the largest of the toothed whales and the largest toothed predator. One interesting fact, does anyone know how they sleep. Its looks kind of strange, but still is one of nature’s marvel.

This is how Sperm Whales sleep.

The sperm whale can be found anywhere in the open ocean. From the early eighteenth century through the late 20th the species was a prime target of whalers. The head of the whale contains a liquid wax called spermaceti, from which the whale derives its name. Spermaceti was used in lubricants, oil lamps, and candles. Ambergris, a waste product from its digestive system, is still used as a fixative in perfumes. Occasionally the sperm whale's great size allowed it to defend itself effectively against whalers. The species is now protected by a whaling moratorium, and is currently listed as vulnerable by the IUCN.
