The Second Seal
Grayson looks a little concerned with his diving buddy in the video. The more the seal bit his hand, the more concerned he became. Fortunately, the bites don’t appear to be severe. The seal appeared to be attempting to amuse the diver.

Grayson then opted to relinquish control to the seal. Meanwhile, the second seal decided that it was his turn to be noticed and began sniffing Grayson’s feet. Perhaps he was getting more trustworthy or desiring attention after witnessing the other seal being lavished with affection.
