Habitat: French Polynesia
Status: No Conservation Concerns

This is an itty bitty microscopic hyperiid amphipod, a small aquatic crustacean that is found exclusively in marine environments – not in freshwater. Hyperiids are distinguished by their large eyes and planktonic habitat. 
Most are parasites or predators of jellyfish and salps. This particular hyperiid amphipo,  known as a Jewel Beetle Amphipod for it’s stunning resemblance to an iridescent beetle (Euthamneus cf rostratus), was found hitching a ride on a jellyfish in Moorea, French Polynesia. It’s kind of gross, but also kind of really beautiful.
