8. Dragon Fish
The dragon fish is a known to be a ferocious predator despite of its small size. It belongs to the crazy deep sea fish. This fish has a large head, a big mouth with many sharp teeth.
The length of the body of an adult dragon fish is about six inches long. Attached to its chin is a barbell on which a photophore (light producing organ) is tipped. It is though the waving back and forth of the photophore that the dragon fish lures smaller fish for prey.
