| Pyramodon ventralis Smith & Radcliffe, 1913 |
Pyramodon ventralis is a pearlfish of the family Carapidae, found in the Indo-western Pacific oceans at depths of between 100 and 400 m. Its length is between 25 and 30 cm.
Pyramodon ventralis is similar in shape to the rattails with a long tapering eel-like body ending in a pointed tail. Both the dorsal and anal fins start about a quarter of the body length from the snout and end at the fused pointed tail fin. The pectoral fins are large and paddle-shaped, but the pelvic fins are reduced to a singe short filament.
Pyramodon ventralis is scaleless and, very unusually, has three lateral lines, as well as a scattering of other sensory pores on the body. The eyes are large and set well forward. The wide mouth contains large canine teeth along the front of each jaw, and a large single vomerine fang.
