Rimicaris kairei

Rimicaris kairei is a species of hydrothermal vent shrimp originally discovered in August 2000 by the operators of the ROV Kaiko from the R/V Kairei, being named for both the ship and the Kairei vent field on which they were first discovered. The shrimp have chemosynthetic symbiotic bacteria that live in their guts which gives them energy. Polymorphism is observed, which is based on different concentrations of iron minerals in the environment, which are deposited under the carapace of these shrimp. They are protogynous, and have epipelagic larvae.
