Very special thanks for the first photo of Malacoctenus gilli to Marcus_z1 from flickr.
Malacoctenus gilli is distributed in the western Atlantic from Bermuda, the Bahamas, in the Gulf of Mexico from Veracruz and northwestern Cuba, and throughout the Caribbean
The Dusky blenny most often inhabits sandy substrata with rocks or boulders but can be found in a variety of habitats from the shoreline to a depth of 5m, seagrass beds, and patch reefs.
It is cryptically colored and difficult to see. It can be found in association with Condylactis sea anemones.
The blenny is preyed upon by the Trumpetfish Aulostomus maculatus.
