Dusky jawfish

The Dusky jawfish, Opistognathus whitehurstii, is a species characterized by its overall dusky or bluish-gray coloration, often with lighter underparts. It originates from the Western Atlantic, including areas like the Gulf of Mexico and the Bahamas. This species is noted for its elongated body, large mouth, and behavior of burrowing into the substrate, where it tends to dwell in burrows it creates. In the aquarium hobby, the Dusky jawfish is not considered one of the most well-known or common species, partly due to its specific care requirements and tendency to hide.
