What looks like a grisly end for a little shrimp is actually a study in symbiosis in this winning picture from the 2005 Visions of Science Photographic Awards.

Photographer Jim Greenfield took the picture off the coast of Curaçao in the Dutch Antilles islands. The image shows a lizard fish opening wide for a shrimp, while the shrimp cleans its teeth of parasites. The photo took top honors in the Action category of this year's competition, which fielded some 2,200 entries
