The Mediterranean rainbow wrasse (Coris julis) is a small, colourful fish in the family Labridae. It can be found in the Mediterranean Sea and in the northeast Atlantic Ocean from Sweden to Senegal (though it is a rare wanderer to the southern British Isles). [3] [2] Records of this species south from Senegal and the Cape Verde Islands are actually the closely related Coris atlantica . [2]

Contents

It feeds on amphipods, isopods, sea urchins, polychaete, shrimps, and small gastropods. [2]

Description

Female near Livorno (Mediterranean population) Coris julis 14-07-05 female.jpg
Female near Livorno (Mediterranean population)

Like many wrasses, C. julis is a sequential hermaphrodite: all start in the smaller initial phase. These initial-phase individuals (both females and males) can turn into the larger secondary-phase males. [4] At a length of about 18 cm (7.1 in), all individuals are secondary-phase males. [2] The maximum length for the species is 25 cm (9.8 in). There is a marked difference in the appearance of the two phases. In the Mediterranean Sea, the secondary-phase male is green, blue, or brown, with white belly, a dark blue spot over the ventral fin, and a bright orange band on the side, while the smaller primary-phase females and males are brown with yellowish sides and white bellies. [5] Populations in the Atlantic differ in colour and genetics from the Mediterranean population, but are maintained in a single species at present. [1] [4] If found to be separate, the scientific name Coris festiva (at present considered a synonym of C. julis) is available for the Atlantic population.

Habitat

It is typically found near the shore in places with seagrass or rocks. It is usually found at depths of 0–60 m (0–197 ft), but occurs as deep as 120 m (390 ft). [2]

<span class="mw-page-title-main">Wrasse</span> Family of ray-finned fishes

The wrasses are a family, Labridae, of marine ray-finned fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into nine subgroups or tribes. They are typically small, most of them less than 20 cm (7.9 in) long, although the largest, the humphead wrasse, can measure up to 2.5 m (8.2 ft). They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera Bodianus, Epibulus, Cirrhilabrus, Oxycheilinus, and Paracheilinus hide among the tentacles of the free-living mushroom corals and Heliofungia actiniformis.

<span class="mw-page-title-main">Ballan wrasse</span> Species of fish

The ballan wrasse is a species of marine ray finned fish from the family Labridae, the wrasses. It is found in the eastern Atlantic Ocean, where it inhabits rocky areas. Like many wrasse species, it is a protogynous hermaphrodite—all fish start life as females, and some dominant fish later become males. It is used as a food fish in some areas and it is also finding use as a cleaner fish in the aquaculture of Atlantic salmon in northwestern Europe.
