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).
Baleen is a filter-feeder system inside the mouths of baleen whales. The baleen system works when a whale opens its mouth underwater and the whale takes in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.ome whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of the whale.
