Naoki is more than happy to let go of the fish, what's left of it, and pull his hands back. He grins at Kisame, and since he doesn't know how to sign 'can I pet your shark', he makes the signs for danger, fish, then mimes petting the hand used to make the fish sign followed by indicating himself and then the general request for a yes or no response.

He'll need to surface soon, but he's still got time.
