Earth Day isn't just about life on land. It's also an opportunity to explore the organisms that inhabit the oceans.
The University of Miami's Rosenstiel of Marine and Atmospheric Science hosts an annual photo contest for the best snapshot of life under the sea. More than 600 images were submitted from an international pool of photographers.
This shot of two transparent gobies, taken in MarsaAlam, Egypt, claimed the top prize as the best overall photo of the competition.
Explore some of the other photos to claim top prizes in the 2011 underwater photography contest in this slide show.
