Labrus

Labrus is a genus of fish in the family Labridae, commonly known as wrasses. These fish are found in the North Atlantic Ocean and the Mediterranean Sea. There are 15 species in the genus, some of which are popular targets for recreational fishing. Labrus species are known for their colorful and vibrant patterns, which vary depending on the species and individual fish.

Characteristics

Labrus fish are generally characterized by their elongated, compressed bodies, with a pointed snout and a small, protrusible mouth. They possess a single, dorsal fin that runs along the length of their backs, and their scales are ctenoid, meaning they have comb-like projections. They are typically carnivorous, feeding on a variety of invertebrates and small fish. Some species, like the cuckoo wrasse (Labrus mixtus), are known for their unusual breeding behavior, where females lay eggs in the nests of other wrasses and leave the male to care for them.

Environments

Labrus fish are commonly found in rocky reefs, kelp forests, and seagrass beds, where they can find shelter and prey. They prefer areas with moderate water currents and depths ranging from the intertidal zone to depths of several hundred meters. Some species, such as the ballan wrasse (Labrus berggylta), are more tolerant of colder waters and can be found in the North Atlantic Ocean, while others, like the dusky wrasse (Labrus merula), are more common in the warmer waters of the Mediterranean Sea.
