Eared Blenny

Cirripectes auritus

The Eared Blenny, also known as the blackflap blenny, is a small reef-associated fish found in the Indo-West Pacific region. It typically reaches a maximum length of 7.1 cm. Its body is elongated and oval in cross-section, with a variable coloration that can range from pale to brown, often with tiny dark spots on the posterior half to three-quarters of the body. The species is distinguished by its unique nuchal flaps, which are black, and its smooth lower lip. The inner ring of the iris is yellow, while the outer ring is reddish-brown. Eared Blennies inhabit coral reefs and are usually found at depths ranging from 0 to 20 meters, although they are most commonly seen between 0 and 10 meters. They prefer environments with coral rocks, sandy bottoms, or rocky substrates with sparse live coral. These blennies are solitary and can often be spotted on shallow protected reefs with rich coral and algae growth. This species is oviparous, with distinct pairing during reproduction. The eggs are demersal and adhere to the substrate via a filamentous pad. The Eared Blenny is assessed as Least Concern on the IUCN Red List and poses no threat to humans.
