Appearance

It reaches maturity at in length and specimens from the Arctic and subarctic, which grow to the largest size, can reach up to . The fish has a squat appearance, a large spiny head and a tapering body. It is a mottled grey-brown in colour but can be darker, including black as base coloring. It has a large mouth and spiny gill covers. The shorthorn sculpin is not venomous, but it can be mistaken for similar looking venomous fishes, notably

s, which allow it to survive at temperatures around or slightly below freezing. It was known that sculpin have been affected by heavy metal exposure in West Greenland by a former lead (Pb) - zinc (Zn) mine. Through analyzing samples of three different sites, a positive correlation was found between fish at a closer distance to the mine and mucus secretion. This mucus creates a layer over the body that can cause respiratory stress, irregular swimming, and also affects their relationships with parasites. Researchers are hoping to use this mucosal mapping to help better understand effects of contaminant and parasite exposure for future studies. They feed on a wide range of
