A marine fish of the Oarfish family in the order Odonata (illustration). This fish is known for its deep-sea peculiar appearance. Its body is strongly compressed and elongated like a ribbon, with no scales on its surface, but instead covered with a dense covering of low, wart-like protrusions. The outer edge of the lower jaw is vertical, and the mouth can protrude forward. The dorsal fin begins on the head and reaches the tail, with rays 1 to 6 stretching out to form a crest. The pelvic fins are elongated and thread-like, widening slightly at two points along the way and at the tip, and the caudal fin is also thread-like. It has no anal fins. The body is silvery-white, and each fin is red. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
