Sea hare

The sea hare, also known as the bearded seal (lat. Erignathus barbatus), is a predatory pinniped mammal of the true seal family, the only representative of the genus and species of sea hare.

The beast received its original name due to the uncharacteristic method of movement for seals: animal flippers are strongly shifted to the neck, and while moving on ice, the bearded force tightens the back of the body, and makes a sharp forward throw, really resembling a hare's jump.
