Alex Mustard - Big Mouth
This large super male napoleon wrasse (super male means he started life as a female, but is now a extra large, dominant male) was forraging on the reef while I was photographing him. Suddenly he turned towards me and yawned in a classic threat display. I was slightly concerned for a second, as I’ve never seen any aggression from this species, until I realised that there was another large male behind me and moments later this fellow raced off in pursuit, keen to drive the intruder from his territory.
