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).
Whales are divided into two suborders â toothed and baleen whales â and each eats very different kinds of food. Toothed whales eat fish, squid, and other animals, while baleens eat plankton, krill, and other small creatures.rcas work tpgether to catch prey larger than themselves. Whale's eat a variety of foods, and their diets may have been impacted by humans. Humpbacks are one of the many whale species that feed on plankton. A blue whale can eat 8,000 pounds of food a day to store reserves for winter.
