This image was captured by Exodus tour guide and wildlife photographer Paul Goldstein.

A lemon shark bites another on the snout in waters off the Bahamas. Photographer Matt Heath said: "The sharks in this picture were competing for a piece of fish that I was hand-feeding them.

Unluckily for the first lemon shark, the second one missed the fish and caught this guy on the nose."
