Tom Hynes' outstanding photo of his Blackray Shrimp Goby (Stonogobiops nematodes).
The entertaining Shrimp Gobies derive their name from their unusual behavior of sharing their burrows in the sand with various small shrimp, such as the Pistol Shrimp. These Gobies warn their shrimp room mates (which have poorer eyesight) of approaching danger in time for them both to retreat into their burrow. In return, the shrimps share their food with the Gobies.
