How often do gray whales eat?

Gray whales are baleen whales, which means they filter food from the water using baleen plates instead of teeth. Their diet primarily consists of small crustaceans like krill and amphipods.

Here's how often they eat:

* During their feeding season in the Arctic and subarctic waters, gray whales feed almost constantly. They spend about 16 hours a day grazing on the seafloor, consuming up to 3 tons of food daily.

* During their migration to warmer waters, they fast for extended periods, sometimes for several months. They rely on their stored fat reserves for energy during this time.

In summary, gray whales eat frequently and heavily when food is abundant, but they can also go for long periods without eating while migrating.
