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



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.

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

Global distribution

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


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

  • 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.
