thepredatorblog: The Pacific Blackdragon is a deep sea fish, that can be found up to depths of up to 3,300 ft. Female blackdragons are about two feet long and have fang like teeth and a long chin whisker. They are black on the outside, as well as on the inside to prevent light from swallowed bio-luminescent prey shining out. The males are small, about three inches in length, and brownish in color. They have no teeth, no chin barbel and no stomach, unable to eat.
