Overview

Comprehensive Description

Biology

Adults are found near rocks and eel-grass beds. A nest of seaweed (Cystoseria) built and kept by male. Feed on bryozoans, hydroids, tubicolous, worms, shrimps, amphipods and mollusks. Males grow faster than females (Ref. 4742). Undergoes sex reversal (Ref. 4742). Oviparous, distinct pairing during breeding (Ref. 205).

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species lives in small groups, mainly over algal-covered rocky substrates, but also in seagrass beds. It feeds on bryozoans, hydroids, tubiculous polychaete worms, shrimps, amphipods and molluscs. The young fish may act as cleaners of other fishes.

It is a protogynous hermaphrodite, and the male builds, maintains and guards a nest made of seaweed (Cystoseia), in which several females lay their eggs (Golani et al. 2006).

The ocellated wrasse, Symphodus ocellatus, is a species of wrasse native to the eastern Atlantic Ocean and throughout the Mediterranean Sea, the Black Sea, and the Sea of Azov. It inhabits areas with rocks and eelgrass at depths from 1 to 30 m (3.3 to 98 ft). It feeds on various marine invertebrates. This species can reach 12 cm (4.7 in) in standard length. It can also be found in the aquarium trade.[2]
