Scale-rayed Wrasse

Overview

The Scale-rayed Wrasse (Acantholabrus palloni) is a solitary, reef-associated fish typically found in temperate marine waters. It is widely distributed across the eastern Atlantic Ocean, from Norway down to Gabon, and is also present throughout the Mediterranean and Adriatic seas.

Distribution & habitat

This species primarily inhabits coastal waters near rocky or sandy bottoms, often seeking shelter in crevices, caves, or near overhangs. While it is frequently found at greater depths, it can occasionally be encountered in shallower rocky areas, particularly in northern parts of its range.

Appearance

This wrasse has an elongated, fusiform body with a pointed snout. Its coloration is generally olive-brown on the back, fading to a lighter shade on the sides and white on the belly. Key identification features include a dark spot on the upper part of the caudal peduncle and another distinct dark mark on the soft portion of the dorsal fin, just behind the spiny section.

Biology & behavior

As a solitary hunter, the Scale-rayed Wrasse feeds primarily on benthic invertebrates. During the breeding season, the species exhibits distinct pairing behavior. Males are known to construct dish-shaped nests and will actively guard the eggs until they hatch.
