Gray Whale Feeding Habits
Gray whales are baleen whales that filter small crustaceans like krill and amphipods from the water.
During their feeding season in Arctic and subarctic waters, gray whales feed almost constantly—about 16 hours a day—consuming up to 3 tons of food daily.
During migration to warmer waters, they fast for extended periods, sometimes several months, relying on stored fat reserves.
In summary, gray whales eat heavily when food is abundant but can go long periods without eating while migrating.
