Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Body deep and compressed sideways with a single long dorsal fin. Maximum length 25 cm but usually less than 15 cm. Colour highly variable and depends on background and age of individual. Females and juveniles tend to be brown or greenish-brown, males are typically more brightly coloured. Both sexes have lines on the head and gill covers which are brown and pale blue in the female, bright green or blue in the male. All corkwing wrasse have a black spot in the middle of the tail stalk and a comma shaped spot behind the eye.

Recorded distribution in Britain and Ireland

Widely distributed on British coasts but most frequent in the south and west.

Global distribution

From Norway to Morocco, the Azores, Mediterranean and Adriatic.

Habitat

On rocky shores amongst seaweed and in lower shore pools, extending sublittorally to depths of up to 50 m.

Identifying features

  • Body length 15 cm, maximum length 25 cm.
  • Black spot in the middle of the tail stalk.
  • Comma shaped spot behind eye.
  • Lines on head and gill cover.
  • Single long dorsal fin with 14-17 spines anteriorly and 8-10 rays posteriorly.
  • Anal fin with 3 spines and 8-11 rays.
  • Lateral line with 31-37 large scales.
  • Mouth small, teeth in a single row on each jaw.
  • Pre-operculum distinctly serrated.

Additional information

Males build an elaborate nest of seaweed in either rock crevices or amongst seaweed or seagrasses in sediment areas. The nests are a ball or mound with an entrance hole, which the males aggressively guard. The distinctive tail spot and mark behind the eye may fade in captive individuals.
