Eurythoe complanata

Eurythoe complanata is a species of polychaetes belonging to the family Amphinomidae. It inhabits coral reefs, such as Heliopora reefs, in the Marshall Islands. The waters surrounding the island of Elugelab, prior to its destruction, had Heliopora coral growth which was home to this species along with Haplosyllis spongicola. Most of the Elugelab specimens are now dead or dying.
