Common to very common in suitable coastal habitats.
Not considered threatened; no specific conservation status is currently known for the species in the Mediterranean.
Native Mediterranean species.
The Striped Blenny (Parablennius rouxi) is a small but highly characteristic inhabitant of the rocky coastal habitats around Cyprus. Divers frequently spot it resting on rocks, among algae, or in small crevices, where it keeps a watchful eye on its surroundings. Thanks to its small size, expressive appearance, and curious behaviour, it is a favourite subject for underwater macro photographers.
Where to Find in Cyprus: Dive Sites & Habitat
The Striped Blenny (Parablennius rouxi) is widespread throughout the Mediterranean and is regularly encountered along the coasts of Cyprus. It is particularly common on rocky reefs, boulder fields, and in areas with abundant algal growth. The species typically inhabits shallow waters between 1 and 20 metres depth, although it can also be found considerably deeper. Divers frequently encounter Striped Blennies at coastal dive sites in the regions of Protaras, Cape Greco, and Ayia Napa. Due to its strong site fidelity, an individual often remains in the same crevice or on the same rock for extended periods.
Behavior & Key Features Underwater
The Striped Blenny (Parablennius rouxi) is one of the most curious reef fish in the Mediterranean. It is often seen perched conspicuously on a rock, observing divers from a safe distance. When threatened, it can disappear instantly into cracks or beneath stones, but will often return a short time later. During the breeding season, males defend small territories and guard the eggs deposited within them. Its striped pattern provides effective camouflage among algae-covered rocks and reef structures. For underwater photographers, the Striped Blenny is a rewarding subject, as it frequently remains still for short periods and displays distinctive, characterful behaviour.
