Role WHAT DOES IT LOOK LIKE?
This large blenny measures from around twelve to thirty centimetres. It has an elongated but heavy body, a rounded forehead and prominent eyes.
Dark vertical bands and paler mottling cross the brown body. Ocular tentacles, branching skin filaments above the eyes, form little tufts, particularly large in males.
A long fin follows the back. The skin has no scales and is covered with mucus, a slippery protective substance.
WHERE DOES IT LIVE?
It frequents algae-covered rocky bottoms between about 3 and 30 metres. Holes and crevices provide refuges.
It is more active at dusk, as light fades, but can still be watched during the day. It moves close to the bottom and its shelters.
WHAT DOES IT EAT?
It eats crustaceans, molluscs, worms and echinoderms, animals such as sea urchins. Algae accompany these animal prey.
Its small mouth contains short, powerful teeth. Food is found in the same rocky surroundings that provide shelter.
