Red-Orange Ghost Shrimp

Corallianassa longiventris

The Red-Orange Ghost Shrimp, belonging to the family Callichiridae, is a crustacean found in the Western Central Atlantic region, including the USA, Martinique, Virgin Islands, Belize, and Jamaica. This species is typically found in shallow tropical waters, residing at depths ranging from 0 to 4 meters. It prefers benthic environments, often burying itself up to a meter deep among coarse sand and coral rubble at the edges of lower intertidal and subtidal seagrass beds. This shrimp is a deposit feeder, primarily consuming seagrass debris that accumulates in its burrow chambers. Its burrowing behavior is an essential aspect of its lifestyle, as it draws seagrass blades into its burrows for feeding. The Red-Orange Ghost Shrimp exhibits a unique mating behavior characterized by a precopulatory courtship ritual that involves olfactory and tactile cues, typically resulting in indirect sperm transfer. Divers encountering this species may find it challenging to spot due to its cryptic nature and tendency to remain buried. Observing these shrimp requires patience and a keen eye for the subtle signs of their presence, such as small mounds of sand or seagrass blades protruding from the substrate. Currently, there is no evaluation of its conservation status by the IUCN.
