Fish of the day
This unique image of the underside of a large stingray was captured on expedition 2 at the wreck of the SS Yongala. The Yongala tragically sunk off the coast of Townsville, Queensland, Australia in 1911, it now provides refuge for 1000's of marine creatures and is considered one of the greatest dive sites in the world.
Most stingrays, like most sharks, are dark on top with a lighter colouring on their undersides - this helps them to lend in against their background (light underside and bright sunlight when seen from below, dark topside against dark bottom when seen from above).
Photographer Lynton Burger uses a strobe flash to illuminate his subject at depth which means we can clearly see the mouth and gils of this stingray in this shot.
