Whales are large, warm-blooded marine mammals categorized into baleen whales, which filter organisms like krill, and toothed whales, which hunt prey using echolocation. These animals utilize blubber for insulation and engage in complex behaviors, including sophisticated communication through songs and whistles, as well as long-distance migrations between feeding and breeding grounds.

While historical population declines were driven by commercial hunting, contemporary threats to whale species include pollution, underwater noise, ship collisions, entanglement in fishing gear, and shifting ocean ecosystems.
