What is Seal?

Seal is the semi-aquatic mammal that hails from phocidae family and lacks external flaps. They are refereed as earless or true seals. The other seal we know as in the pinnipeds group is fur seal, which belongs to the family Otariidae and has external ear flaps. The Seal here being referred is the true seal belonging to phocidae family and it is characterized as due to lack of the external ear flaps. Seals use back flippers while swimming and use the front flippers for the steering purpose when swimming. As they can’t rotate their back flippers they use front flippers to make the movement on land which is generally a caterpillar like movement. Seals have spot and patches on their body which is another of their physical feature differentiating it with other look-alike aquatic animal apart from lacking external ear flaps and having claws and fur on front flippers which help them move on land.

Unlike Seals, their rear flippers can also rotate and with them they can even walk or run on the land.

They have large front flippers as compare to the Seals, though they lack claws or fur on it.
