IdentificationEdit

The body of this wrasse is deep set, with a reasonably large rounded head, small eyes, and a large mouth with thick lips. Small teeth are to be found in a single row in the jaws, with enlarged teeth at the front.

The preoperculum (gill cover) is greatly serrated, both on the lower edges (ventrally), and on it's rear (hind edge).

It sports a long based dorsal fin with two connected sections. The anterior is composed of 14 to 17 membrane bound spines, whilst the posterior portion has 8 to 10 branched rays. The anal fin normally has 3 anterior spines followed by 8-10 branched rays. The interorbit area is naked of scales. There is 1 scale behind the eye, whilst the opercle region is more or less scaled. The body scales are large, with 4.5 to 5.5 rows between the base of the dorsal fin and the lateral line. Some 32 to 36 body scales run the length of the lateral line.

Colouration is highly variable, although usually green to greenish brown, with darker pigmentation associated with the back and upper sides, whitish belly, with body scales highlighted by brownish spacing. A black smudge is to be found in front of the fin rays of the tail, below the lateral line. There is often a crescent shaped dark patch behind the eye. Males have blue/green, wavy or curved lines on the head.

BreedingEdit

Spawns from May into July, with the construction of algal nests in intertidal crevices that are then guarded by the male. Hatch at about 2.5 to 3mm, are planktonic for a short time, before taking up residence in the intertidal zone. Mature at 10cm (ie 2 to 3 years as females).

HabitatEdit

The most common intertidal wrasse, found over algae covered rocks, from the mid-tide down to 30m or so. Often found in tidal pools from the mid-shore down. Young wrasse often encountered in eel-grass beds.

FoodEdit

Juveniles act as cleaner fish, and remove parasites from other fish species, whilst older individuals feed on a range of molluscs and crustaceans.

RangeEdit

Found all around the coasts of the UK.
