Apri l'appDescrizione
Labrus viridis, commonly known as the Green Wrasse, is a vibrant and relatively large wrasse species found in the Mediterranean Sea and adjacent Atlantic waters. It is characterized by its striking green coloration, which can vary in intensity and pattern, and its robust body shape. This species plays an important ecological role in its benthic habitat.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- Predominantly bright green, often with iridescent blue or yellow markings, especially on the head and fins. Some individuals may exhibit darker mottling or banding, particularly juveniles or during specific behavioral states. The intensity of green can vary geographically and with age/sex. Males tend to be more vibrantly colored.
- Tipo di squame
- cycloid
- Posizione della bocca
- terminal
- Caratteristiche distintive
- Robust, elongated body, Large, prominent lips, Terminal mouth with strong canine-like teeth, Continuous dorsal fin with spiny and soft-rayed portions, Often displays a dark spot at the base of the pectoral fin, Can reach up to 50 cm (20 inches) in total length, though typically observed between 25-40 cm (10-16 inches)
- Pinna dorsale
- Single, long dorsal fin with 18-21 spines and 9-12 soft rays. The spiny portion is longer than the soft-rayed portion.
- Pinna caudale
- Rounded to slightly truncate caudal fin.
- Pinna pettorale
- Large, fan-shaped pectoral fins, typically with 13-15 rays.
- Pinne distintive
- Pelvic fins are thoracic, located directly below the pectoral fins. All fins are generally green, often with blue or yellow margins or streaks.
Consigli per l'identificazione
Coloration
Look for the characteristic bright green body. While other wrasses can be green, Labrus viridis typically has a more uniform and intense green hue, often with iridescent blue or yellow accents.
Size and Body Shape
Its relatively large size (up to 50 cm) and robust, elongated body distinguish it from many smaller wrasse species.
Head and Mouth
Observe the large lips and prominent, canine-like teeth, indicative of its predatory diet.
Habitat
Often found in rocky areas and seagrass beds, which helps narrow down identification among wrasse species.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found in shallow coastal waters, from 1 to 50 meters (3 to 164 feet), occasionally deeper.
- Ambiente
- Prefers rocky reefs, seagrass beds (Posidonia oceanica meadows), and areas with abundant algal growth. Juveniles often inhabit shallower, more sheltered areas. They are benthic fish, closely associated with the substrate.
- Areale geografico
- Eastern Atlantic Ocean, from Portugal to Morocco, including the Azores, Madeira, and Canary Islands. Widely distributed throughout the Mediterranean Sea, including the Adriatic and Aegean Seas.
Informazioni sull'acquario

- Temperamento: semi-aggressive
- Dieta: carnivore
- Dimensione minima della vasca: 250 gallons
- Temperatura: 18-24°C (64-75°F)
- Livello di pH: 8.1-8.4

- Compatibilità: Best kept in a species-specific tank or with other large, robust fish that can tolerate its territorial nature. Avoid keeping with smaller, docile fish or invertebrates.
- Requisiti speciali: Requires a large tank with ample rockwork for hiding and establishing territories. A deep sand bed is beneficial as they may bury themselves at night or when stressed. Excellent filtration and stable water parameters are crucial. Not typically recommended for home aquaria due to size and specific needs.
Informazioni in natura

- Sapore: Mild, slightly sweet
- Consistenza: Firm, flaky white flesh
- Metodi di cottura: Baked, Grilled, Fried, Steamed
- Valore nutrizionale: Good source of lean protein, omega-3 fatty acids, and various vitamins and minerals.
Fatti chiave
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
This species is a benthic carnivore, primarily feeding on small crustaceans (crabs, shrimp), mollusks, echinoderms (sea urchins, brittle stars), and other small invertebrates found on the seabed.
Territorial Behaviorbehavior
Adult males are highly territorial, especially during the breeding season, and will actively defend their nesting sites and harems of females.
Nest Buildingbehavior
Males construct nests from algae and seagrass, often in crevices or under rocks, where females lay their eggs. The male then guards the eggs until they hatch.
Nocturnal Behaviorbehavior
At night, Green Wrasses often bury themselves in the sand or hide in rock crevices to sleep, protecting themselves from predators.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: Generally safe to handle, but like all fish, care should be taken to avoid fin spines, which can cause minor punctures. They have strong jaws and teeth, so direct contact with the mouth should be avoided. No known venomous properties.

Labrus merula
While also a large wrasse, Labrus merula is typically brown or bluish-brown, lacking the vibrant green of Labrus viridis. It also has a more pointed snout and a different pattern of markings.
Ballan Wrasse
Labrus bergylta
Labrus bergylta is generally more mottled in coloration, ranging from green to brown to reddish, and often has distinct white or pale spots. Its body is typically deeper and more compressed than L. viridis.
Ornate Wrasse
Thalassoma pavo
Thalassoma pavo is smaller and has a more slender body. While it can exhibit green coloration, it is characterized by distinct blue and red stripes and a more pointed head. It also has a different fin morphology.
