Whales are large, warm-blooded marine mammals categorized into two main groups: baleen whales, which use flexible plates to filter organisms, and toothed whales, which hunt prey using teeth and echolocation. These mammals utilize blubber for insulation and undergo significant migrations between feeding and breeding grounds.

While historical commercial hunting led to population declines, current threats to whale species include pollution, underwater noise, ship collisions, fishing gear, and changing ocean ecosystems.
