Cayman Cleaner Goby

Elacatinus cayman

The Cayman Cleaner Goby is a small reef-associated fish found in the tropical waters of the Western Atlantic, specifically around the Cayman Islands. It reaches a maximum length of 2.3 cm and is easily recognizable by its distinctive coloration. The upper part of its head and body is black, contrasted by a pale middorsal streak behind the head. A wide iridescent blue lateral band runs along the body, containing a midline yellow stripe that extends from the tail to the snout, forming a V or U shape at the front. This yellow stripe maintains a uniform width, setting it apart from similar species. Divers encountering the Cayman Cleaner Goby will find it in coral reefs, where it is known for its cleaning behavior. It lacks scales and has an inferior mouth with a complete upper lip groove. The species is harmless to humans and plays a role in the reef ecosystem by cleaning other fish. Despite its ecological importance, the Cayman Cleaner Goby is categorized as Endangered on the IUCN Red List, highlighting the need for conservation efforts in its habitat. Divers may observe these gobies perched on corals or rocks, waiting to clean passing fish. Their small size and unique coloration make them a notable find for those exploring the reefs of the Cayman Islands.
