Green Coral Shrimp

Coralliocaris graminea

The Green coral shrimp, a member of the family Palaemonidae, is a small crustacean found in tropical and subtropical regions of the Indo-Pacific. It inhabits depths ranging from 1 to 12 meters, often residing on hard substrates in reef-associated environments. This shrimp is typically found in association with scleractinian corals, contributing to its common name. The Green coral shrimp is part of the order Decapoda, which is characterized by mostly gonochoric species. These shrimp engage in precopulatory courtship rituals, relying on olfactory and tactile cues. Mating involves indirect sperm transfer, a common trait among decapods. Divers encountering the Green coral shrimp may find it in shallow waters, often hiding among coral formations. Observing this shrimp requires a keen eye due to its potential cryptic behavior and habitat preferences.
