The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Zeugopterus regius - Eckström's Topknot

Habitat & Distribution

Syn. Phrynorhombus regius (Bonnaterre). Prefers rough, stony ground where it clings to the undersides of rocks at 10-55m depth of water. It is also occasionally caught in sandy bays. It occurs along the western sea-board of Europe from the Mediterranean to northwest Scotland and all around the coast of Ireland, but is rarely seen.


Certain fishing techniques, such as scallop dredging, will result in some habitat damage and disruption.
