Description

The red gurnard (Chelidonichthys cuculus), also known as the East Atlantic red gurnard, is a benthic fish species of Triglidae family. Widespread in the Eastern Atlantic from British Isles (occasionally Norway and Germany) to Mauritania (including Madeira and Azores). Also known throughout the Mediterranean and possibly in the Black Sea. They also occur around Queensland, Western Australia, New South Wales, New Zealand, South Africa, Japan and China. Gurnards are very distinctive bottom-living fish with large heads and eyes. The head is protected by large bony plates and strong spines. The lower three rays of the pectoral fins are separate, finger-like processes that contain sensory organs. These are used by the gurnard to 'feel' for small fish, crustaceans and other invertebrates living in the sediment. The red gurnard has a stout body, large head, leathery skin and eyes and moderately large scales. It is one of the smallest of the European gurnards reaching a maximum length of 40 cm (16 in). They live for up to 10 years and live on the sea bed at a depth of 150 meters, but can live between 100 and 400 meters in depth. The coloration is bright red with pinkish-silver mottling on the sides and head. The protective bony plates on the head which are characteristic of all gurnards are very conspicuous in this species. Along the lateral line there is a row of large, plate-like scales. The divided dorsal fin has nine spines and seventeen to eighteen soft rays while the anal fin has no spines and sixteen to eighteen soft rays. The red gurnard is native to the temperate eastern Atlantic Ocean and the Mediterranean Sea. Its range extends from southern Norway and Sweden southwards to the British Isles, France, Spain, Madeira, the Azores and the coast of Africa as far south as Mauritania and around S. Africa. It is also present in the Mediterranean Sea and parts of Australasia, the south west pacific and possibly the Black Sea. Its depth range is from the surface down to about 400 m (1,312 ft) but it is most usually found between 30 and 250 m (98 and 820 ft). It is found over sand, shingle or rocky seabeds and feeds on bottom-dwelling invertebrates, such as crustaceans, and also small fish.
