Montagu's blenny (Coryphoblennius galerita)

Summary

Description

Coryphoblennius galerita is a small, scaleless, elongate blenny with eyes on top of its head and a down-turned mouth. It reaches 8.5 cm in length and is pale brown in colour with olive green vertical stripes and pale blue spots. It has a single dorsal fin that stretches the length of the body with a distinct notch part way down. It is distinguishable from other British blennies by the fringed fleshy crest between its eyes, continued by a series of short fleshy tentacles along the dorsal surface. As with all blennies, the pectoral fins are large and the pelvic fins are modified into thin 'limbs' that are used to grip rock in the intertidal zone.

Recorded distribution in Britain and Ireland

Recorded around southwest Britain from Pembrokeshire to Dorset and the south coasts of Ireland.

Global distribution

Southwest Britain to northwest Africa. Occasionally in the Mediterranean.

Habitat

Occurs around mid-tide level in the rocky intertidal where it feeds on the limbs of barnacles. It prefers pools without much foliose seaweed cover and is most often found in pools with substantial amounts of coralline algae.

Depth range

Identifying features

  • A crest on the head commences with an erectile fringed flap between the eyes and continues with a line of short tentacles along the dorsal surface.
  • The single long dorsal fin is divided unequally by a conspicuous notch.
  • Blue-white spots cover the body, which is pale brown with green patches/stripes.

Additional information

Coryphoblennius galerita may be confused with the shanny, Lipophrys pholis, as they co-occur in the range of Coryphoblennius galerita. With close examination they can be distinguished by the fleshy crest and blue-white spots of Coryphoblennius galerita.
