Tetralia cavimana

Tetralia cavimana is a small crab species belonging to the family Tetraliidae, commonly found in the Western Indian Ocean, specifically in regions such as the Persian Gulf, Oman, and the Red Sea. This species is known for its commensal relationship with Acropora coral species, where it plays a protective role against predators like the crown-of-thorns starfish, Acanthaster planci. The crab's presence can be beneficial to the coral, as it helps maintain the health of the coral by deterring these predators. The habitat of Tetralia cavimana is primarily benthic and tropical. The species has been recorded near various dive sites. The species is considered harmless to humans and has not been evaluated by the IUCN for conservation status.
