Red Gurnard – Aspitrigula Cuculus

Description

Gurnard are very distinctive with a large bony head with spines  and a steep profile. The front of the large pectoral fin is divided to form three fingel-like feelers. These are used to find food in the sediments. They are red in colour with a light coloured underside.

Habitat

Red Gurnard around most of the British Isles except the east coast. It lives on sandy or muddy bottoms. Inshore you find young individuals as shallow as 5m of water and can live down to 200m. Gurnard sit on the bottom on their feelers or lie flat on the sediment. They can be easily approached by divers and make good photographic subjects. When caught they can make a grunting noise. This is made by muscles in the wall of the swim bladder. It is believed that the noise is to communicate with others in the small shoal.

Spawning

Gurnard spawn in spring and early summer. The eggs and larval fish float freely in the plankton.

Lifespan

Red Gurnard grow to about 30-40cm.

Food

Gurnard eat mainly crustaceans such as crab and shrimp.
