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).
These species are broken down into two suborder known as Baleen Whales and Toothed Whales. Baleen whales in general tend to be much larger than their toothed whale counterparts, however there are much more species of toothed whale than there are in the baleen whale suborder. Part of this is due to the fact that dolphins and porpoises are also a part of the toothed whale suborder.
