Coloration
The vibrant green body is the most distinguishing feature. While other wrasses can be green, Labrus viridis typically has a more uniform and intense green hue.
Size
Can grow up to 50 cm in length, making it one of the larger wrasse species in its range.
Lips
Its thick, fleshy lips are quite noticeable and characteristic of the Labrus genus.
Pectoral Fin Spot
Look for a dark spot, often black or dark brown, at the base of the pectoral fin, though its presence and intensity can vary.

Nøkkelfakta
Protogynous Hermaphroditebehavior
Labrus viridis is a protogynous hermaphrodite, meaning individuals are born as females and can later change sex to become males. This is a common reproductive strategy among wrasses.
Dietary Habitsbehavior
Its diet primarily consists of small invertebrates such as crustaceans (crabs, shrimp), mollusks, and echinoderms (sea urchins, brittle stars). It uses its strong jaws and teeth to crush shells.
Nest Buildingbehavior
Males build nests from algae, often in crevices or under rocks, where females lay their eggs. The male then guards the eggs until they hatch.
Longevityinteresting
Green Wrasses can live for up to 15-20 years in the wild, making them a relatively long-lived species among coastal fish.
Cleaning Behavior (Juveniles)behavior
Juvenile Labrus viridis have been observed engaging in cleaning behavior, removing parasites from other larger fish species, similar to cleaner wrasses.
Sikkerhetsinformasjon
Trygg- Sikkerhetsnivå: safe
- Giftig: Nei
- Spiselighet: edible
- Håndteringsnotater: Generally safe to handle, but like all fish, care should be taken to avoid fin spines, which can cause minor punctures. No known venomous properties.
