What is the purpose of baleen plates in whales?
A whale’s baleen plates play the most important role in its filter-feeding process. To feed, a baleen whale opens its mouth widely and scoops in dense shoals of prey (such as krill, copepods, small fish, and sometimes birds that happen to be near the shoals), together with large volumes of water.
How do baleen whale adapt to their environment?
These adaptations enable a baleen whale to conserve oxygen while underwater. Baleen whales, like other mammals, have a slower heart rate while diving. When diving, blood is shunted away from tissues tolerant of low oxygen levels toward the heart, lungs, and brain, where oxygen is needed most.
