Cyclopterus lumpus


The Lumpsucker is a large, lumpy fish which lives amongst seaweed and rocks around or below the low tide mark. Their pectoral fins form a suction ring that enables them to 'stick' to rocks around the surf zone, preventing it from being washed away by the waves.

How to identify

Unmistakeable; rounded, with small lumps and no scales, bluish-grey in colour, the males have an orangey belly.

Where to find it

Found all around our coasts but most common around Scotland.

How can people help

Lumpsuckers and other small fish provide a vital link in the food chain for many of our rarer species. Our seas and coastline are in need of protection if we are to keep our marine wildlife healthy. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives. This work has recently had a massive boost with the passing of the Marine Bill, promising sustainable development of the UK's marine environment. Do your bit for our Living Seas by supporting your local Wildlife Trust.
