	Sperm Whale - MSN Encarta
		Sperm whales probably split off from the ancestors of all present-day cetaceans about 20 million years ago, and they may be as closely related to the baleen whales as they are to other toothed whales and dolphins.
		The bodies of sperm whales are laterally compressed, with a single blowhole on the left front of the head and a thick dorsal hump originating at the hindmost third of the body.
		Sperm whales were hunted intensively by American whalers during the 1800s for the light oil of their heads, and by factory ships of several countries in the 1900s for their meat.

		Sperm whales are usually dark, brownish grey, while the skin around the mouth and often patches on the underside of the body are white.
		Sperm whales exhibit the greatest sexual dimorphism of any cetacean, with females averaging 10 m (35 ft) in length and a weight around 12 tonnes-1/3 to1/5 of the weight of their male counterparts (although size differences vary between oceans depending upon exploitation, when larger males in particular were targeted by whalers).
		Sperm whales were easy prey for whalers as it was well known that members of a group would come to the aid of a companion in distress, so by injuring a single member of the pod, the whalers were often able to pick off the entire herd one by one.

	Sperm Whale (Physeter macrocephalus)
		Sperm whales are worldwide in distribution and occur in all oceans, including Arctic and Antarctic waters, but are primarily found in temperate and tropical waters of the Atlantic and Pacific Oceans.
		Sperm whales are the most numerous of the great whales in the Gulf of Mexico and sightings near the Texas coast are relatively common.
		In spite of the danger, sperm whales were hunted the world over for the array of valuable products these whales contained — whale oil for lamps and lubricants; spermaceti (oil from the forehead) for high quality, smokeless candles; and ambergris, a waxy by-product of digestion which was used in the manufacture of fragrances.

		Whales have one or two nostril openings, called blowholes, located far back on the top of the head; the nostril valves close and the lungs compress when the whale dives.
		There are three families of baleen whales: the right whale family (Balaenidae), including the bowhead, or Greenland whale; the gray whale family (Eschrichtidae), with a single species (Eschrichtius robustus) found in the N Pacific Ocean; and the rorqual family (Balaenopteridae).
		The family includes the humpback whale, the sei whale, the minke whale, the Bryde’s whale, the fin whale (or common rorqual), and the blue whale, which can grow to a length of 100 ft (30 m) and a weight of 150 tons.

		Sperm whales are found in most of the world's oceans, but they do not enter most semi-enclosed or shallow seas such as the Baltic and the North Sea; they are well-known in the Mediterranean though.
		Consequently, all threats relate to man. Sperm whales are subject to organised killing for almost 400 years, mainly for the oil produced from their thick blubber, and for the wax found in the head - known as spermaceti.

		On their skin, sperm whales often bear circular scars that match the suckers on a giant squid's tentacles—indicating that it isn't always easy for the whale to get a meal.
		Scientists know that sperm whales prey upon the giant squid, but the squid's diet is unknown—the stomachs of most specimens are empty.
		Between meals, sperm whales gather in social groups—females with young whales, and mature males in "bachelor pods." Only older bull males tend to be solitary.
