A very small flattened fish with a tapered head. A single dorsal fin at the rear of the body opposite the anal fin. Pelvic fins fused into a suction cup. Variable bright colours, notable a bright red, usually but often with two ocellated spots which may be hidden by the pectoral fins. It has a broader head than the similar fish with a ridge on the top of the head and without the broad stripe across the head. 

Similar species: Apletodon dentatus

Breeding:  Summer (probable) 

Habitat:  In shallow water, but rarely intertidal, and less likely to be found in kelp holdlfasts than the similar species. 
Food: Small crustaceans (probable) 

Range: British coasts, mostly in south and west with the only BMLSS records from the south Cornish coast. Records from the Cullercoats area, Newcastle, and from the coast of Norway. 

Additional Notes:  Records prior to 1971 may be the similar species. 
Information supplied by Andy Horton (BMLSS) with helpful information from Jon Makeham (Looe) and Frank Moen (Norway).

A sighting of the Two-spotted Clingfish.
Location: at depth of 15 metres in Loch Creran, near Oban
Time of finding: 15:20 hrs
Finders: Dan Reynolds and Bryony Robinson
Means of identification: fish was photographed in situ - see below

The small goby in this picture distracts the viewer's attention away from the distinct red partially ocellated spot on the flanks of the clingfish

Prevalence: Only one fish found in five dives in near vicinity, on the south shore of the upper part of Loch Creran, about half a mile above the narrows.
Other details: Fish around 40-50 mm in length. Generally remained curled, did not move from a small area despite disturbance, showed ability to point eyes in different directions.
"I think it was the two spotted species because of the red spot on the side and the relatively big head. There's a picture that looks particularly similar on Fishbase - both the reddish cheek and the red spot."
