Two-Banded Seabream

Diplodus prayensis

The two-banded seabream, Diplodus prayensis, is a marine fish species unique to the Cape Verde Islands. It features an oval, compressed body with a mouth that can slightly extend. Divers can recognize this fish by its distinct dental structure, which includes brown, incisor-like teeth at the front and molar-like teeth arranged in a semicircular pattern. Its body displays a mix of brownish to greenish shades with alternating gold and grey lines along the scales. Key identifiers include a dark head with a light patch on the nape, a dark line along the edge of the gill cover, and a black spot at the base of the pectoral fin. A dark band on the caudal peduncle becomes more evident in mature individuals. This species can reach a maximum length of 35 cm, though 25 cm is more common. Found in the eastern Atlantic Ocean, the two-banded seabream inhabits the waters surrounding the Cape Verde Islands, taking the place of its close relative, D. vulgaris, in this region. It thrives on rocky substrates at depths up to 100 meters and can also be found on muddy bottoms at greater depths. Its diet consists of invertebrates and seaweed, playing a role in the local marine ecosystem. The two-banded seabream is targeted by artisanal fisheries in Cape Verde, where it is sold fresh. The IUCN lists it as Least Concern. Divers might observe this species calmly moving over rocky or muddy substrates, making it an interesting subject for underwater photography.
