Alex Mustard - Hitchhiker
A predatory bandcheek wrasse (Oxycheilinus digrammus) hides underneath a hawksbill turtle (Eretmochelys imbricata) to enable it to sneak closer to small reef fish, its prey. Hawksbill turtles feed on corals and sponges, so reef fish know that they are not a threat. By hiding in this way the wrasse is able to get much closer to a potential meal. This is quite a common behaviour and I have even had these wrasse hiding underneath me in a similar way.
Location: Gulf of Suez, Egypt
