Yes, whales are mammals, however due to the fact that they live in the ocean these large animals are referred to as marine mammals. In fact the blue whale is the largest living mammal (and animal species) on this earth. In terms of size the blue whale can grow to lengths of over 90 ft. long and weigh more than 150 tons.
The blue whale is the largest animal ever known to have existed. During the 20th century, the species was almost exterminated due to commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a number of serious threats including ship strikes and the impact of climate change.
