How do whales feed without teeth?

Baleen whales feed without teeth by using baleen plates to filter food from water. They take in large gulps of water and prey, such as krill and small fish, and then push the water out through their baleen, trapping the food inside. This method, known as filter feeding, allows them to consume large quantities of food efficiently. Species like blue whales rely on this specialised feeding strategy to sustain their massive size.
