Icelinus

Icelinus is a genus of sculpins, belonging to the family Cottidae. These small, bottom-dwelling fish are primarily found in the marine waters of the North Pacific Ocean, though some species may also inhabit brackish or freshwater environments.

Icelinus sculpins are characterized by their relatively small size, typically reaching lengths of less than 15 centimeters. They possess a robust body shape, often with bony plates or prickles covering their skin. Their coloration is typically cryptic, allowing them to blend in with the substrate of rocks, sand, or algae.

The diet of Icelinus sculpins consists mainly of small invertebrates, such as crustaceans and mollusks. They are ambush predators, lying in wait for prey to come within striking distance.

Several species are recognized within the genus Icelinus, each with its own specific geographic distribution and morphological characteristics. Some of the more commonly known species include:

• Icelinus borealis (northern sculpin)
• Icelinus filamentosus (threadfin sculpin)
• Icelinus fimbriatus (fringed sculpin)
• Icelinus quadriseriatus (fourline sculpin)

The conservation status of Icelinus species varies depending on the particular species and the threats it faces. Some species may be relatively common and widespread, while others may be more vulnerable due to habitat loss or other factors. Further research is often needed to fully assess the conservation needs of individual Icelinus species.
