LUMPSUCKER or LUMPFISH
Cyclopterus lumpus
©Laura Quick
While I had hoped to see them swimming aimlessly around, the lumpfish, true to form were suitably, well, lumpy. They are kind of cute in their own way. This one, is bluish in color and lives at the Sea Life Trust Beluga Whale Sanctuary / Sæheimar Aquarium in Heimay, on the Vestmannaeyjar in Iceland.
Lumpfish generally have bodies that are ball-like. They have a knobbly, ridged back and three large bony tubercles on each flank. Their pelvic fins form suction discs which it uses to attach strongly to rocks or other surfaces. The head and the pectoral fins of males are larger than those of females. It has a jelly-like layer of fat under the skin. Its color is highly variable; bluish as this one, greyish in the link below, olive, yellowish or brownish. Mature males turn orange-reddish during the breeding season.
