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).
Most whales migrate to eat and breed. For example, baleen whales feed mostly on krill, which is abundant in very cold waters. However, these cold waters are not a suitable environment in which to give birth â newborn calves are born without a protective blubber layer under their skin and would quickly freeze to death.or example, baleen whales feed mostly on krill, which is abundant in very cold waters.
