Blackflap Blenny – Facts and Photographs

Blackflap Blenny (Cirripectes auritus) also known as the Eared Blenny

The Blackflap Blenny (Cirripectes auritus) also known as the Eared Blenny and the Black-eared Eyelash Blenny. They are combtooth blennies that make their home in holes, usually in corals and sponges.

 
APPEARANCE

The Blackflap Blenny obtains its common name from the characteristic flap on the back of the head. These flaps vary in colour from blue to black, circled with yellow.  The body is a typical goby shape with a large blunt head with proportionally prominent eyes giving it a good field of vision. The dorsal and anal fins are continuous and extend the length of the body. Their pectoral fins are prominent and are used for perching. On the head there are several small sensory pores.

The head is usually a red brown colour with small white markings around the eye. The eye is ringed in red with a thin inner yellow line and there are usually several yellow white bars on the lips. On the top of the head are two antler like cirri which are usually orange tipped in yellow. Below the eye there are two smaller red cirri. Behind the head the body is usually a light yellow brown colour which lightens into a whitish colour towards the tail.  There are a series of small brown dots randomly scattered across the body.

BACKFLAP BLENNY IN THE WILD

The Blackflap Blenny is fairly common in Tanzanian waters if one knows where to look for them. They are usually found on larger coral features with their head protruding from a hole.  On odd occasions as one swims up to a feature they are seen out in the open, but quickly shoot back into their hole.  From there they observe the diver, sometimes opening their mouth and posturing.  Any slight movement from the diver and they withdraw into their holes.  The holes vary from being in coral to holes in sponges.  They are never seen far off the bottom and usually make short skips from one spot to another, always staying close to their hole which they are quick to jump back into. They are usually seen solitary but sometimes there is only a distance of 30 cm between two holes with one blenny in each.

AQUARIUMS

Blackflap Blenny are not commonly kept in tanks. However they have a lot of character and can make a pleasing addition to a tank. They are relatively easy to care for. They may jump so a well sealed tank is a must.
