Blue whales do not catch fish in the traditional sense. As baleen whales, they possess baleen plates instead of teeth and rely on a method called filter feeding.
The Feeding Process
- Opening wide: Blue whales open their mouths enormous, engulfing huge volumes of water filled with krill, small fish, and other tiny organisms.
- Baleen filtering: Their keratin baleen plates act like a giant sieve. Bristles trap krill and food while water is pushed out through the sides of the mouth.
- Swallowing: Once the water is expelled, the whale swallows the concentrated food trapped in the plates.
Blue whales do not actively chase individual fish. Their filter-feeding strategy is incredibly efficient for consuming massive quantities of small prey.
