How to Identify Red Gurnard

To identify Red Gurnard (Chelidonichthys kumu), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

The dorsal surface is typically reddish-brown to bright red, often mottled with darker patches. The flanks are paler, transitioning to a white or silvery belly. The most striking feature is the large, fan-like pectoral fins, which are often iridescent blue or green with dark spots and a bright blue margin, especially prominent in adults. Juveniles may have less intense coloration.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Large, bony head with a steep profile and prominent ridges and spines., Three free, finger-like rays on each pectoral fin, used for 'walking' on the seabed and sensing prey., Large, fan-like pectoral fins with vibrant blue/green coloration and dark spots., Two distinct dorsal fins.

Dorsal fin

Two dorsal fins: the first is spiny (7-10 spines), and the second is soft-rayed (15-17 rays).

Tail fin

Caudal fin is slightly emarginate (forked) to truncate.

Pectoral fin

Large and fan-like, extending beyond the anal fin origin. The lower three rays are free and thickened.

Distinctive fins

Pelvic fins are thoracic, located beneath the pectoral fins.

Identification Tips

1. 1

   Pectoral Fins

   Look for the large, fan-shaped pectoral fins with their characteristic iridescent blue or green coloration, often adorned with dark spots and a bright blue edge. The three free lower rays are also a key identifier.

2. 2

   Head Shape

   The large, bony head with a steep profile and prominent ridges and spines is distinctive for gurnards. The Red Gurnard's head is particularly robust.

3. 3

   Coloration

   The overall reddish-brown to bright red body color, often mottled, helps distinguish it from other gurnard species, though color can vary with habitat and depth.

4. 4

   Body Spines

   Feel for the sharp spines on the head and operculum (gill cover). These are a common feature of gurnards.
