The fluctuating temperatures in the core depend on pressure, the rotation of the Earth, and the varying composition of core elements. In general, temperatures range from about 4,400Â° Celsius (7,952Â° Fahrenheit) to about 6,000Â° Celsius (10,800Â° Fahrenheit).
Baleen whale (suborder Mysticeti), also called toothless whale, any cetacean possessing unique epidermal modifications of the mouth called baleen, which is used to filter food from water. Baleen whales seek out concentrations of small planktonic animals. The whales then open their mouth and take in enormous quantities of water. When the mouth is closed, they squeeze the water out through the sides, catching the tiny prey on the baleenâs bristles. (See also cetacean: Feeding adaptations).
Whale Uses Baleen Fashion Utilitarian. Baleen. Until the end of the 19th century it was baleen, rather than oil, that was the primary product sought by the Greenland whalers. Confusingly, baleen was always known as whale-bone by the whalers and by those who used it in manufacture. It is not bone, but a derivative of skin! Baleen whales eat small, planktonic crustaceans such as copepods and krill, or small shoaling fish including herring and sardines. These whales have no teeth, instead, they feed by straining their food from the sea using a series of baleen plates that are made of keratin, the same material that forms your hair and nails and the hooves and horns of cows.
