Juvenile Play of the Common Seal Phoca Vit Ulina Vit Ulina With Comparative Notes On the Grey Seal Halichoerus Grypus
Abstract Juveniles of the common seal, Phoca vitulina, have two kinds of aquatic play : (1) Dyadic play, in which muzzle-to-body and body contact between two animals is combined with exuberant somersaulting movements. The somersaulting behaviour is usually preceded by a contact phase with very littl...
