Viperfish
There are many deep parts in our planet which is home to many rare species like the viperfish. Due to its difficult lifestyle scientist were unable to find the exact figure of this species. It is estimated that they can live up to 30-40 years in the midst of the wild.
During day viperfish prefer to stay deep under water to avoid sun light and during night they can be seen in shallow waters. A viperfish is found in various colors. So far they are spotted in silver, black and green.
Scientist found it to be one of the fiercest predators under the depths of the sea. And are known to attack their prey by attracting them by producing light from their light producing organ called a Photophore. It is located at the end of their dorsal spine. They flash their natural light on and off. They also use their light producing organ to communicate with potential mates. They use their fang teeth to immobilize their prey and couldn't close their mouth because of their length.
The vertebra behind the head of the viperfish is mainly to absorb shock of the attacks, which are targeted against Dragonish and other small creatures under water. They can live for a very long time without food. As they live in extreme depth under water, they are somehow separated from human activity and have very little impact on them.
God has created so many weird beautiful creatures that we are not aware of and there are many of them whom we haven’t seen yet. One life can never be enough to have see all of his creation.
