Recorded distribution in Britain and IrelandRecorded from southwest and northeast England, north Wales and west Ireland but is probably distributed all around Britain and Ireland.
HabitatFound in pools on rocky shores and on sublittoral rocky ground to 27 m. It prefers rocky areas with plenty of algal cover and may also be found in seagrass beds.
- Long eel-like body with second dorsal fin and anal fin extending along most of the body-length.
- Three barbels; one above each nostril and one on the lower jaw.
- Two dorsal fins; the first is reduced to a fringe of very short rays that may be seen moving with a continuous wave-like motion.
- Mottled dark brown colour.
Additional informationMay be confused with the five-bearded rockling Ciliata mustela, because they are similar in colour and habitat. But as the name suggests, the five-bearded rockling can be distinguished from Gaidropsarus mediterraneus by the five barbels around its mouth. The three-bearded rockling, Gaidropsarus vulgaris also has three barbels around its mouth but can be distinuguished from Gaidropsarus mediterraneus because of its very different colouration, which is reddish brown with obvious blotches.
