The Arctic Shanny, scientifically known as Stichaeus punctatus, is a species of fish belonging to the family Stichaeidae. This fish is characterized by its elongated body, reaching a maximum size of 22.0 cm. Its distribution spans across various marine zones, primarily found in depths ranging from 0.0 to 100.0 meters.
Description & Characteristics
The Arctic Shanny, Stichaeus punctatus, is a slender and elongated fish with a distinctive body shape. Its body is covered in numerous small scales, and its coloration varies depending on its habitat. The Arctic Shanny can be identified by its small mouth, positioned at the tip of its pointed snout. It possesses a single, dorsal fin that extends along the length of its back, as well as an anal fin that runs along its ventral side. This fish has a rather small caudal fin, which is often rounded in shape.

The Arctic Shanny, Stichaeus punctatus, is a common inhabitant of the North Atlantic Ocean. It can be found in both coastal and offshore waters, frequently observed in areas with rocky bottoms and abundant kelp forests. This species is known to occur in the neritic zone, a marine environment extending from the shoreline to the edge of the continental shelf. The Arctic Shanny is generally found at depths between 0.0 and 100.0 meters, where it prefers to inhabit areas with ample food sources and suitable shelter.
Taxonomy
The Arctic Shanny, Stichaeus punctatus, is classified within the Class: Teleostei, Order: Perciformes, and Family: Stichaeidae.
