Rimicaris kairei is a species of hydrothermal vent shrimp originally discovered in August 2000 with the ROV Kaiko on the R/V Kairei[1]. They are named for the R/V Kairei and the Kairei hydrothermal vent field on which they were first discovered.[2] They get energy from chemosynthetic symbiotic bacteria that live in their gut.[3] They reproduce sexually and have a larval stage in which they consume photosynthetic material.[4]Rimicaris kairei lives on four different hydrothermal vent sites on the Central Indian Ridge in the Indian Ocean.[2] They are the most populous invertebrate on these vents.[5] The species is differentiated from other species of Rimicaris Shrimp by a lack of setae, longer flagellar antennae, and less robust pereopods.[2]
