Spotted Seabass

Overview

The spotted seabass (Dicentrarchus punctatus) is a temperate marine fish belonging to the Moronidae family. Closely related to the European seabass, it is widely recognized by the distinct dark spots scattered across its back and flanks, as well as a prominent black mark on its opercle.

Distribution & habitat

This species is primarily found in the Eastern Atlantic Ocean, ranging from the English Channel southward to Senegal and the Canary Islands. It is also common throughout the Mediterranean Sea and the Gulf of Suez. It thrives in coastal marine and brackish environments, frequently inhabiting sandy, muddy, or rocky bottoms. It is highly adaptable and may occasionally be found in estuaries, harbors, and even river mouths.

Appearance

The spotted seabass features an elongate, silvery-grey body with a bluish back. Key diagnostic characteristics include two separate dorsal fins, a moderately forked caudal fin, and a relatively deep caudal peduncle. Its opercle bears two flat spines, while the lower margin of the preopercle is lined with large, forward-pointing spines. The vomerine teeth form an anchor-shaped patch that extends toward the midline of the palate.

Biology & behavior

As a voracious predator, the spotted seabass is exclusively carnivorous. It is often observed in small groups, particularly near structures like piers and breakwaters, or in shallow, oxygenated coastal waters. It is a hardy species capable of tolerating a variety of environmental conditions, including hypersaline habitats. Spawning typically occurs in winter, between December and March, in water temperatures ranging from 12 to 14°C.
