Its unique characteristics, fascinating behavior, and vital role within its ecosystem make it a subject of great interest to marine biologists and enthusiasts alike.
Description & Characteristics
The Ctenolabrus rupestris is distinguished by its slender, elongated body, which can reach a maximum size of 18.0 cm. Its coloration is striking, with a deep blue to green body adorned with bright yellow or orange spots.

The mouth of the Ctenolabrus rupestris is small but capable of opening wide, revealing a set of strong, pointed teeth that aid in its predatory lifestyle.
Habitat and Occurrence
The Ctenolabrus rupestris is a species that thrives in a variety of habitats. Its preferred environment includes rocky reefs and coastal waters, often found at depths ranging from 1.0 to 50.0 meters. This adaptability allows the species to inhabit both the intertidal zone, where it encounters the ebb and flow of tides, and deeper, more stable waters. Its distribution extends across various marine zones, making it a common sight in the northeastern Atlantic Ocean, the Mediterranean Sea, and the North Sea.
Taxonomy
The Ctenolabrus rupestris belongs to the Class: Teleostei, Order: Eupercaria incertae sedis, and Family: Labridae. The family Labridae encompasses a diverse range of species, including wrasses, parrotfish, and hogfish, all of which share characteristic features like their colorful scales and prominent lips.
Feeding
The Ctenolabrus rupestris is a voracious predator, relying on a diet consisting mainly of invertebrates. Its prey includes amphipods, bryozoans (sea mats), clams, copepods, crabs, crustaceans, edible crab, rock lobsters, sea squirts, snails, starfishs, worms, and zoobenthos. This varied diet reflects the species’ ability to adapt to diverse environments and exploit different food sources.
