Black Dragon fish – it glows! It’s invisible! It has razor sharp teeth

dragonfish1

The black dragonfish can be very hard to find because they can make themselves invisible anytime. How can  they make themselves invisible? Well, you can’t see it but there is a red dot behind its eye. They can be really camouflaged. You can hear them but you will have to guess where the dragon fish is. The dragon fish has razor sharp teeth, which is one of its creature powers. The sharp teeth helps the dragonfish grab and kills its prey. The dragon fish has a special lure that glows like the frog fish, that helps catch and confuse its prey because many shrimp are chasing for bio-luminescence (producing their own light).  When the shrimp comes close to the bio-luminescence, the dragon fish catches it.
