Appearance
The streaked gurnard has a large triangular, bony head which bears many ridges and spines and with a deep occipital groove. There are two separate dorsal fins, the first contains between 9 and 11 spines while the second dorsal fin, and the anal fin, both have between 14 and 17 fin rays. The body is covered in clear, oblique ridges of skin starting on the lateral line. The breast may or may not have scales but the belly is scaled. The scales of the lateral line are enlarged and have small spines on them. The upper body is red, marked with dark spotting on the head and the back with a paler lower body. The pectoral fins are greyish marked with large dark blue spots. The three lower pectoral fin rays are separated from the rest of the fin. The head has an almost vertical profile on the snout.
