Introduction

[edit]

The '"Spoonhead Sculpin"' (‘’Cottus ricei’’) is a freshwater fish that lives in North America and Canada. This species is not as common as its cousin species the mottled sculpin.

Range

[edit]

The spoonhead sculpin can be found in Canada from southern Quebec to the Mackenzie River in the Northwestern and Yukon Territories and in British Columbia. They are also found in northern Ohio, Montana, and in many of the Great Lakes like Lake Superior and Lake Erie.[1] The spoonhead is also a native Montana fish that can be found in the St. Mary and Waterton river drainages of Glacier National Park. They are generally found in fast flowing rivers and deep lakes. .[2]

Physical description

[edit]

They do not have scales but instead are covered in small, fine, curved spines. They have a flat triangular shaped head and a cylindrical shaped body. They also have very defined preopercular spine. Their fins are long and round and their coloration ranges from greenish brown to light yellow and their bodies are speckled. Spoonhead sculpins average length is about 1.5 to 2.4 inches, however, the largest sculpin on record was 5.3 inches. .[3] Their eyes are positioned on top of their head and they have a very large mouth. They also have a complete lateral line, this allows them to detect movement in the water. .[4]> These fish usually live to be 6 years old compared to slimy sculpins that usually live for 5 years and deepwater sculpins live for 7 years. [5] The spoonhead sculpin does not contain a swim bladder. Also they are most sensitive to low frequencies of sound and are less sensitive to high frequencies of sound. [6]

Distribution

They are also found in northern Ohio, Montana, and in many of the Great Lakes like Lake Superior and Lake Erie. [7]. The spoonhead is also a native Montana fish that can be found in the St. Mary and Waterton river drainages of Glacier National Park. They are generally found in fast flowing rivers and deep lakes.
