The Gray Whale is a large marine mammal known for its long migrations and distinctive gray coloration. These whales can grow up to 50 feet long and weigh as much as 40 tons. They primarily feed on small crustaceans, such as amphipods, by filtering them from the ocean floor. Gray whales are known for their unique feeding behavior, which involves rolling on their sides to scoop up sediment. Gray whales are found in the North Pacific Ocean, migrating between their breeding grounds in Baja California and feeding areas in the Arctic. They are known for their friendly nature and often approach boats. The species was once endangered due to whaling but has made a significant recovery since the practice was banned.
