What is the difference between a Seal (Pusa) and a Sea Lion (Neophoca)?
A Seal and a Sea Lion are both pinnipeds – finned semi-aquatic marine mammals. A Walrus (Odobenus rosmarus) is also a pinniped.
A Seal and a Sea Lion both have flattened heads with white whiskers.
A Seal has short flippers that are thinly webbed with a claw on each small toe, whereas a Sea Lion has large skin-covered flippers.
On land, a Seal wriggles on its belly, whereas a Sea Lion walks on its flippers.
A Seal has no visible ear flaps (external ears), whereas a Sea Lion has visible ear flaps.
A Seal is quiet and grunts, whereas a Sea Lion makes a ‘barking’ noise.
A Seal is mostly solitary, but can live in colonies, whereas a Sea Lion lives in large groups of up to 1,500 individuals.
A Seal is smaller than a Sea Lion. A Seal grows to about 130 centimetres (51 inches), whereas a Sea Lion grows to about 180 centimetres (71 inches).
The female Seal and the female Sea Lion give birth to one live young, called a pup.
