Cyclopterus is a noun that refers to a genus of marine fish commonly known as lumpfish. It belongs to the family Cyclopteridae and is characterized by its unique appearance and morphology. The word "cyclopterus" originates from the Greek words "kyklos," meaning circle or wheel, and "pteron," meaning wing, which describe its rounded body shape and pectoral fins.
These fish are typically small in size, with an average length between 20 to 40 centimeters, although some species can grow up to 70 centimeters. Cyclopterus species are widely distributed across the northern Atlantic Ocean, particularly in colder waters, including the Arctic and subarctic regions.
The distinguishing features of the cyclopterus include its thick, scale-less skin and a unique disk-like structure on the ventral surface. This disk, called an adhesive disc, is composed of modified pelvic fins and is used by the fish to cling onto rocks, seaweed, or other surfaces. The fish can produce a natural adhesive substance that helps it adhere firmly to these surfaces, allowing it to resist strong water currents.
Lumpfish are known for their peculiar appearance, with a slightly flattened body and a deep, rounded head. They have small, rounded eyes and protruding lips. These fish feed primarily on invertebrates, small crustaceans, and various types of plankton.
In addition to their ecological role, cyclopterus are noteworthy for their economic value. The females of some species produce roe, commonly known as lumpfish caviar, which is harvested for culinary purposes and is particularly appreciated as a substitute for sturgeon caviar.
