The North Atlantic right whale swims slowly through the sea with its small front flippers. It keeps its large body on track with its broad, transverse tail fin. It swims slowly, only 8 km per hour. As it glides through the water, it filters small crabs and fish through the baleen in its mouth, which it then devours. A meal like that takes quite a long time for him. Since the sea giant weighs up to 100 tons, it can eat a lot of crabs.
