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 whales hunt for food using a variety of techniques. One common technique these marine mammals use is known as filter feeding in which these large animals swim around with their mouths open and filter food through their baleen bristles (which often resemble the teeth found on a comb).n order for whales to capture their food these marine mammals search and hunt for their prey using a variety of techniques in order to locate, isolate and immobilize their prey for easy consumption.
