Cyclopteropsis Jordani, The Smooth Lumpfish

Arctic.uoguelph.ca | 13 April 2002 | The smooth lumpfish is a mysterious species of which very little is known. Only a few specimens have ever been caught and so nothing is known of its biology.

This species can be distinguished from other lumpfish by the gill opening above its pectoral fin, and by the five blunt tubercles found on the anterior part of its body. Its first dorsal fin is rounded and fleshy with 6 spines while the second has 12–13 soft rays. The caudal and anal fins are rounded, with the anal fin containing 10–12 rays. Its pectoral fins are large and fan-like with 23–24 rays. Its body is shaped much like a tennis ball with fins, mouth and eyes. Its overall body colour is likely brownish-grey, and it grows to a length of just 6.1 cm
