Annular Seabream

Overview

The Annular Seabream is a small, silvery marine fish widely distributed across the Mediterranean, Black Sea, and the eastern Atlantic. It is frequently encountered in shallow coastal waters, including seagrass beds, sandy bottoms, and sheltered areas like ports and lagoons.

Distribution & habitat

This species ranges from the Bay of Biscay southward along the coast of Portugal to the Canary Islands and Madeira. It is also common throughout the Mediterranean and Black Seas. While typically found in shallow coastal zones, it is most often associated with Posidonia and Zostera seagrass meadows, though it also frequents sandy areas and rocky environments.

Appearance

Recognized as the smallest member of its genus, the Annular Seabream typically reaches lengths of 13–16 cm, with a maximum of around 24–28 cm. Its body is oval-shaped and laterally compressed, featuring a bright silvery color that often displays yellow tints on the head and fins. The most distinct identification mark is a dark, ring-like spot located on the caudal peduncle. It possesses a protractile mouth equipped with eight incisors followed by rows of molars, which are adapted for crushing its prey.

Biology & behavior

This diurnal species is generally territorial and may be observed swimming alone or in small groups. It is a carnivorous predator that feeds on a variety of small invertebrates, including crustaceans, mollusks, worms, echinoderms, and hydrozoans. While the sexes are typically separate, some individuals may exhibit protandric hermaphroditism. Spawning generally occurs in the spring and early summer, with timing influenced by water temperature.
