Its not a bad photo at all

Its not a bad photo at all considering the size! Good spot.

Unfortunately the id is not as straightforward as it first seems. Some sources including my Marine fishes on Wales book which is normally very good have 2 species a. dentatus and a. microcephalus. Worms ( the best resource on marine taxonomy that I have found says that they are in fact the same species and that a. microcephalus is a synonym. So, so far so good ID wise however there is another species the two-spotted clingfish (Diplecogaster bimaculata) which is identical except for different teeth and in males only the two spots. So this is either a. dentatus or a female two spotted clingfish!

This has been subsequently discussed in proving how valuable iSpot resource is.
