The North Atlantic right whale swims slowly through the sea with its small front flippers. It keeps its large body on course with its wide, 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 eats with relish. Such a meal takes quite a while for it. Since the sea giant weighs up to 100 tons, it can eat quite a few crabs.
