Distribution

Range Description

In the Eastern Atlantic, this Atlanto-Mediterranean species is present from Portugal southwards to around Senegal, including the Azores, Madeira, Canary Islands, Selvagens and Cape Verde Islands. From Senegal southwards along the west African coast to Cape Lopez in Gabon, this species is probably replaced by a separate species, T. newtoni. References to this species occuring in Sao Tome and Principe (Afonso et al. 1999) probably refer to T. newtoni (L. Rocha pers. comm. 2008).

It is found throughout most of the Mediterranean Sea, except for parts of the northern coasts of the western Mediterranean and the Adriatic Sea. It is however found in the Ligurian Sea and around Sardinia (Molinari and Tunesi 2003, Molinari 2005, Tunesi et al. 2006, Tunesi and Molinari 2005, Sara et al. 2004, Guidetti et al. 2004, Guidetti et al. 2008). It is absent from the Black Sea (D. Pollard pers. comm. 2008).

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species inhabits coastal waters near rocks and seagrass beds. It is also often found near man-made structures such as shipwrecks and jetties, etc. (Golani et al. 2006). It is either gregarious, being found in small groups or forming larger aggregations in loose schools, in association with the two types of mating system, territorial haremic or group spawning, respectively (P. Afonso pers. comm. 2008).

It feeds on small molluscs and crustaceans (Quignard and Pras 1986). The juveniles of this species often clean other fishes (Golani et al. 2006).

This species is a protogynous hermaphrodite, with distinct sexual dichromatism (Gomon and Forsyth 1990). It spawns in spring, and the eggs and larvae are planktonic (Golani et al. 2006).

Justification
This species is present throughout most of the Mediterranean Sea and the sub-tropical and tropical coasts of West Africa and the Macaronesian islands, where there are no known major threats to its populations. There is no specific population information available for this species in the north-eastern Atlantic, though overall its populations are thought to be stable. It is therefore listed as Least Concern.

Population

Population
In the Mediterranean Sea, this species is less common in the north-western basin, as it prefers warmer waters. It is mainly common elsewhere.

The population declined in the 1970's in the Ligurian Sea, but is now recolonising this area (Tunesi pers. comm.). This species is now also expanding its range in the Gulf of Lion, where it was not previously present (Quignard pers. comm.). Overall, the wider Mediterranean populations of this species appear to be stable.

It is the most abundant and common wrasse in the shallow rocky habitats of the Azores (Porteiro 1995, Afonso 2002), Madeira (Ribeiro et al. 2005, 2006) and the Canaries (Falcón et al 1996, Brito et al. 2002). It is also common but not as abundant in Cape Verde (Monteiro et al. 2008).

Thalassoma pavo

The ornate wrasse, Thalassoma pavo, is a species of wrasse native to the eastern Atlantic Ocean from Portugal to Gabon and the oceanic islands and into the Mediterranean Sea. This species inhabits areas of rocks and eelgrass in coastal waters at depths from 1 to 150 m (3.3 to 490 ft), though rarely below 50 m (160 ft). It can reach 25 cm (9.8 in) in length, though most do not exceed 20 cm (7.9 in). This species is of minor importance to local commercial fisheries, is also popular as a game fish, and can be found in the aquarium trade.[2]

Synonyms[edit]

Several described species and name combinations have been determined to be synonyms of T. pavo:

  • Thalassoma unimaculatum (R. T. Lowe, 1841)

  • Julis unimaculata taeniata R. T. Lowe, 1841
  • Thalassoma pavo taeniata (R. T. Lowe, 1841)
  • Julis turcica torquata R. T. Lowe, 1843
