Most mysticetes prefer the food-rich colder waters of the Northern and Southern Hemispheres, migrating to the Equator to give birth.During this process, they are capable of fasting for several months, relying on their fat reserves.They spend their lives in the water, having to mate, give birth, molt or escape from predators, like killer whales, underwater.This has drastically affected their anatomy to be able to do so.Cetaceans have well-developed senses—their eyesight and hearing are adapted for both air and water, and baleen whales have a tactile system in their vibrissae.They have a layer of fat, or blubber, under the skin to maintain body heat in cold water.The extinct ancestors of modern whales are the Archaeoceti.
Besides hunting, cetaceans also face threats from accidental trapping, marine pollution, and ongoing climate change.
Male cetaceans typically mate with more than one female (polygyny), although the degree of polygyny varies with the species. Male cetacean strategies for reproductive success vary between herding females, defending potential mates from other males, or whale song which attracts mates.
Calves are typically born in the fall and winter months, and females bear almost all the responsibility for raising them.
A few, such as the killer whale, feed on mammals, such as pinnipeds and other whales.
