Redlight Goby

Coryphopterus urospilus

The Redlight Goby, known scientifically as Coryphopterus urospilus, is a small reef-associated fish found in the eastern-central Pacific Ocean. It inhabits the coastal waters from Baja California, Mexico, down to the Galapagos Islands. This species is typically found at depths ranging from 5 to 40 meters, often residing in the sand-rubble fringes of rocky reefs or among coral patches. Divers may encounter them darting among the rocks, where they forage for tiny crustaceans. Reaching a maximum length of 6.5 cm, the Redlight Goby has an elongated body shape. Its orange spot can resemble sand grains, providing camouflage against the sandy bottoms it frequents. This adaptation is particularly useful as the goby is known for its quick movements and tendency to dive for cover when approached. The Redlight Goby is a benthic spawner, laying its eggs on the ocean floor. Despite its small size, it plays a role in the reef ecosystem by feeding on small crustaceans. The species is currently listed as Least Concern on the IUCN Red List.
