Faceless Cusk:
The faceless cusk (Typhlonus nasus) is a genus of cusk-eel found in the Indian and Pacific Oceans at depths from 3,935 to 5,100 m (12,910 to 16,732 ft). This species grows to 46.5 cm (18.3 in) in standard length.
The fish is named after its appearance due to having an extremely reduced “face”. The mouth is located on the underside of the head. The sides of the head do not display any visible eyes. However, Typhlonus nasus does possess eyes, which can be seen deep beneath the skin in small-sized specimens. It also possesses two pairs of large nostrils towards the front of the head above the mouth. The species has discernible gill covers on each side of the head and large deciduous scales. It also has reduced dorsal and anal fins which are dark in colors and are fused at the end, as a replacement for a lacking caudal fin. The fins of this fish are black in color, with a very pale body.
