About Symphodus tinca (Linnaeus, 1758)
Symphodus tinca, commonly called the East Atlantic peacock wrasse, has an oval, laterally flattened body. Its mouth is rather small, more or less protrusive, and lined with fairly strong canine-like teeth. A small number of cephalic pores are present on the snout, and the lips have 6 to 9 folds. The head is generally longer than the depth of the body. The dorsal fin is very long, extending almost all the way to the tail. Both sexes have a small dark spot at the base of the caudal fin, and a dark blotch positioned just above the pectoral fin. Many darker spots scattered across the body form 3 or 4 longitudinal stripes. The species' overall coloration shows clear sexual dimorphism. Females and juveniles are grey-greenish or brownish, fading to a silvery shade on the belly, and there are almost no visible color differences between immature males and mature females. Males are more brightly colored, particularly during the breeding season; their base color ranges from pale green to green-bluish or green-yellowish, they have longitudinal rows of red spots, and the upper part of their head is dark blue. East Atlantic peacock wrasse can reach a standard length of 44 cm (17 in), though most individuals do not grow larger than 25 cm (9.8 in). Because of their relatively small size, this species is rarely targeted as a game fish, but it is sometimes sold locally for food when caught by small-scale local artisanal fisheries. It is also available in the aquarium trade. The peacock wrasse feeds on sea urchins, ophiuroids, bivalves, shrimps, and crabs. Spawning occurs in spring. During spawning, males build and guard a seaweed nest, and one or more females lay their adhesive eggs inside this nest. This species is native to the eastern Atlantic Ocean, ranging from Spain to Morocco, and is also found in the coastal waters of the Mediterranean Sea and the Black Sea. It is a gregarious littoral fish that lives on algae-covered rocky reefs, in seagrass meadows, around rocks surrounded by eelgrass, and can also occur in brackish lagoon waters. It is found at depths between 1 and 50 m (3.3 to 164.0 ft).
