Members of this genus are found in the North Atlantic Ocean, primarily along the coastlines of North America and Europe.
Common Names

Characteristics
Ctenolabrus species share several key characteristics:
- Elongated, compressed body with a rounded head.
- Prominent lips that are often thick and fleshy.
