Spot-Head Blenny

Parablennius cyclops is a species of combtooth blenny primarily found in the 🌊 Red Sea, a region where it is considered endemic. This small, tropical fish typically measures up to 6 centimeters (approximately 2.4 inches) in length and can be easily recognized by a distinct brown spot located behind its eye. It inhabits marine environments, particularly demersal zones, meaning it often dwells on or near the sea floor.

An interesting aspect of the Parablennius cyclops is its ability to breathe air, a trait known as facultative air-breathing, which is observed within its genus. The species reproduces by laying eggs, a practice known as oviparity. The eggs are notable for being demersal and adhesive, which means they sink to the bottom and stick to surfaces. This sticking occurs via a filamentous adhesive pad or pedestal. The larvae of Parablennius cyclops are planktonic and are commonly found in shallow coastal waters shortly after hatching.

The name "Parablennius" is derived from Greek, with "para" meaning "the side of" and "blennios" meaning "mucus," which could refer to the fish's appearance or behavior.
