About
Observation Post #20 It may take whales until June or July to reach these far arctic feasting grounds. These frigid, oxygen-rich waters teem with the tiny creatures that gray whales eat. The gray whale feeds by diving to the sea floor, turning on its right side and scooping sediment into its mouth. An adaptation called baleen allows these toothless whales to filter their food from huge gulps of water. Baleen is like a wide curtain or fringe in the whales's mouth. The whale squirts out the water, leaving behind herring, krill, and other food it then swallows. A whale may eat a ton of food a day! Photo: Renee Bonner |
