Adiacanthus Fasciola (Peters, 1877) is a fish of the genus Oxytropis in the family macrostomatidae. It is distributed in Taiwan Island and other places. The female can be up to 27 cm long, while the male is only 4 cm long. The odd ratchet lives on the bottom of the sea 500 meters below the water. There is little food there. In such a bad environment, the odd ratchet only opens its big mouth and snares every bit of food. The jaw of a chiropractic can be extended forward to swallow prey larger than it.
