Rimicaris kairei

Species of crustacean

Rimicaris kairei is a species of hydrothermal vent shrimp originally discovered in August 2000 with the ROV Kaiko on the R/V Kairei. They are named for the R/V Kairei and the Kairei hydrothermal vent field on which they were first discovered. They get energy from chemosynthetic symbiotic bacteria that live in their gut. They reproduce sexually and have a larval stage in which they consume photosynthetic material. Rimicaris kairei lives on four different hydrothermal vent sites on the Central Indian Ridge in the Indian Ocean. They are the most populous invertebrate on these vents. The species is differentiated from other species of Rimicaris Shrimp by a lack of setae, longer flagellar antennae, and less robust pereopods.
