The grey gurnard is an abundant demersal species. Gurnards are key predators in the North Sea and have become more important in recent years. In winter they form dense aggregations locally to the northwest of the Dogger Bank, whereas in summer they are more widespread. This fish produces sounds. | |||

The thornback ray is usually found on shallow mud, sand, or gravel seabeds up to 60m depth. It is less abundant in the southern North Sea. Its population levels are presently too low for the ray to fulfill its ecological role. | |||
