Pointed-snout Wrasse

Overview

The Pointed-snout Wrasse (Symphodus rostratus) is a small, slender marine fish endemic to the Mediterranean Sea and parts of the Black Sea. It is easily recognized by its distinctively elongated, concave snout and highly protractile mouth, which it uses to forage among rocky reefs and seagrass beds.

Distribution & Habitat

This species is primarily found in the Mediterranean and the western Black Sea. It favors coastal environments, specifically rocky reef areas and adjacent Posidonia seagrass meadows. It is a diurnal, bottom-dwelling fish that often blends into its surroundings to remain inconspicuous.

Appearance

Typically reaching lengths of 8 to 14 cm, this wrasse has a laterally compressed body covered in large scales. Its coloration is variable, ranging from bright green to greenish-brown, often featuring two dark longitudinal bands on the flanks that may become more or less visible depending on the fish's mood. A white mid-dorsal line is also commonly present.

Biology & Behavior

Pointed-snout Wrasses are generally solitary or found in pairs. They are known for their unique sleeping posture, often resting with their heads tilted downward within seagrass. Their diet consists mainly of small benthic invertebrates, including crustaceans and bryozoans, which they carefully extract using their specialized, narrow mouths.

Reproduction

During the spring breeding season, the male constructs a nest made of algae, often situated on top of a rock. He displays a prominent white mid-dorsal line to attract females. After spawning, the male fertilizes the eggs and remains to guard and aerate the nest until they hatch, while the female provides no further parental care.
