Symphodus melops, commonly known as the Corkwing Wrasse, is a small to medium-sized marine fish belonging to the family Labridae. It is characterized by its robust body, prominent lips, and a distinctive dark spot on the caudal peduncle and another behind the eye. This species exhibits significant sexual dimorphism, particularly during the breeding season, with males displaying more vibrant coloration and developing specialized structures for nest building. They are active, diurnal fish, playing an important ecological role in coastal rocky and algal habitats.

- Highly variable, ranging from greenish-brown to reddish-brown, often mottled or marbled. Males typically exhibit brighter colors, especially during breeding, with iridescent blue or green markings. A prominent dark spot is present on the caudal peduncle and another smaller one behind the eye. The belly is usually lighter.

- Características distintivas
- Two prominent dark spots: one on the caudal peduncle and another behind the eye., Thick, protractile lips., Relatively large scales., Males develop a distinctive 'cork' or algal nest during breeding.

- Single, long dorsal fin with 14-17 spines and 9-11 soft rays. The spiny portion is longer than the soft-rayed portion.

- Rounded caudal fin.
- Nadadeira peitoral
- Large, fan-shaped pectoral fins.
- Nadadeiras características
- Pelvic fins are thoracic, located beneath the pectoral fins.
Dicas de identificação
Coloration and Pattern
Look for the variable greenish-brown to reddish-brown body with mottling. The two dark spots (caudal peduncle and behind the eye) are key identifiers.
Body Shape
Its compressed, robust body with thick lips is characteristic of wrasses.
Fin Structure
The long dorsal fin with more spines than soft rays, and the rounded caudal fin, are typical.
Behavior
Observe its active, inquisitive behavior, often seen foraging among rocks and algae. Males during breeding will be guarding their distinctive algal nests.
Habitat
- Tipo de água
- saltwater
- Profundidade
- Typically found from the intertidal zone down to about 30 meters, occasionally deeper (up to 50 meters).
- Ambiente
- Prefers rocky shores, kelp forests, seagrass beds (Posidonia oceanica and Zostera marina), and areas with dense algal growth. They are often found in crevices and among rocks, seeking shelter.
- Distribuição geográfica
- Eastern Atlantic Ocean, from Norway and the British Isles south to Morocco, including the Azores, Madeira, and the Canary Islands. Also present throughout the Mediterranean Sea and the Black Sea.

Fatos principais
Nest Builderbehavior
Male Corkwing Wrasses are renowned for their elaborate nest-building behavior. They construct nests from pieces of algae, shells, and other debris, cementing them together with a sticky mucus produced from their skin. These nests are then guarded fiercely.
Protogynous Hermaphroditeevolution
Like many wrasses, Symphodus melops is a protogynous hermaphrodite, meaning individuals are born as females and can later change sex to become males. This sex change is often triggered by social cues or environmental factors.
Cleaner Fish Behaviorbehavior
Juvenile Corkwing Wrasses, and sometimes adults, have been observed engaging in cleaner fish behavior, removing parasites from other larger fish species. This symbiotic relationship benefits both the cleaner and the cleaned fish.
Dietary Generalistbehavior
The Corkwing Wrasse is an opportunistic carnivore, feeding on a wide variety of small invertebrates found among rocks and algae, including crustaceans, mollusks, and polychaetes. Their strong jaws and teeth are well-adapted for crushing shells.
Informações de segurança
Seguro- Nível de segurança: safe
- Venenoso: Não
- Comestibilidade: edible
- Observações de manuseio: Generally safe to handle, but like all fish, care should be taken to avoid fin spines, which can cause minor punctures. Return to water quickly if caught.

Goldsinny Wrasse
Ctenolabrus rupestris
The Goldsinny Wrasse is generally smaller, has a more slender body, and lacks the prominent dark spot behind the eye. It typically has a dark spot at the base of the caudal fin, but not on the caudal peduncle itself, and often a dark spot on the anterior dorsal fin.
Ballan Wrasse
Labrus bergylta
The Ballan Wrasse is significantly larger, can reach up to 60 cm, and has a much more robust body. While also variable in color, it lacks the distinct dark spot behind the eye and on the caudal peduncle that characterizes S. melops. Its scales are also larger and more prominent.
Rock Cook
Symphodus tinca
Symphodus tinca is generally larger and has a more elongated body shape. While it can also be variable in color, it typically lacks the distinct dark spot behind the eye and on the caudal peduncle. Its head profile is also often more pointed.
