Pearly Razorfish

Overview

The Pearly Razorfish is a unique, small-bodied wrasse recognized for its highly compressed, blade-like body and steep, blunt head profile. It is widely distributed across the Atlantic Ocean and the Mediterranean Sea, where it is frequently associated with sandy substrates and seagrass meadows.

Appearance

This species features an elongated, laterally flattened body that tapers to a sharp edge at the front of the head, a trait reflected in its scientific name. While coloration varies, individuals are typically pale green, yellow-orange, or reddish-pink, often with a darker back and lighter belly. The head is distinctively marked with a pattern of vertical, light blue and orange lines. Males and females exhibit sexual dimorphism, with differences in head shape and pelvic fin length.

Biology & behavior

The Pearly Razorfish is a diurnal species known for its remarkable ability to dive headfirst into sandy bottoms to escape predators or rest. This sand-diving behavior makes the species highly dependent on specific sediment types, such as coarse or well-sorted sand. It is a protogynous hermaphrodite, meaning individuals can change sex from female to male, a transition often accompanied by changes in color and the adoption of a harem-based social structure.

Feeding

As a benthic predator, the Pearly Razorfish feeds primarily on small organisms found in or on the sand. Its diet consists mainly of mollusks, such as bivalves, as well as crustaceans like crabs and shrimps. Adults typically target larger prey items, while juveniles consume smaller, more vulnerable organisms.
