The Lumpsucker is a scaleless fish that is also known as the Lumpfish and is quite common in the northern waters of England. It spends a lot of time on the bottom of the seabed, but it does move to rocky shallow waters in late winter and early spring to spawn.

The Lumpsucker has an appropriate name because its body is covered in lots of little lumps. It also has a large sucking disc on the underside of its body which it uses to cling onto surfaces. The Lumpsucker can reach lengths of between thirty to fifty centimetres and its body is almost spherical-shaped. It is normally a blue to slate-grey colour, but the male changes to a red, pink and yellow in the spawning season.

The female Lumpsucker lays her eggs on rocks and then leaves shortly afterwards. The male takes over the responsibility of the eggs by clamping itself onto a rock to guard and cover the eggs. When the young hatch out, they look like tiny tadpoles. They usually stay in shallow water or rock pools until they grow bigger. They are often difficult to spot because they hide in between seaweed and rocks.
