Yellow-Headed Goby

Gobius xanthocephalus

The Yellow-headed Goby is a small reef fish found in the eastern Atlantic Ocean, ranging from northern Spain to Madeira and the Canary Islands, as well as in the Mediterranean Sea. It typically inhabits inshore waters at depths from 1 to 36 meters, often residing under stones or within rocky substrates and coralline grounds. This species is also associated with Posidonia oceanica meadows, where it feeds on macrofauna from hard substrates and suprabenthic organisms. Divers may encounter this goby while exploring rocky or seagrass habitats, where its cryptic nature can make it a challenge to spot. Reaching up to 10 centimeters in length, the Yellow-headed Goby is characterized by its fusiform body shape and distinctive yellow head. It has a total of 7 dorsal spines and 14 to 16 dorsal soft rays, along with a single anal spine and 14 anal soft rays. The species is known for its reduced suckers and separated pelvic fins, which help distinguish it from similar gobies. The Yellow-headed Goby is classified as Least Concern by the IUCN. Divers observing this species can enjoy watching its interactions with the surrounding habitat, as it feeds and moves among the rocks and seagrass beds.
