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).
grazers are huge populations of baleen whales (minke Balaenoptera bonaerensis), sh-eating killer whales (Orcinus orca), seals and penguins[9].Indeed,sotight is the predator prey relationship that the seasonal arri-val of the whales forces penguins to change diet from krill to silver sh and dramatically increase their foraging effort.
