Shrimp in Sponge by William Goodwin, National Geographic international photography contest winners.
Winner in the nature category:
Shrimp in Sponge. William Goodwin, US.
This peppermint shrimp is spending the day in a branching vase sponge about 75ft deep in Bonaire's Margate Bay.
Lighting was achieved with an HID torch shining on the outside of the sponge. The photographer, working upside down, had to approach as close as possible without touching or disturbing the shrimp or the sponge
