Giant sea is derived from the Devonian period spanning 415-360 million years ago. In this period, various animals living in the ocean and became the ruler of the earth. Not surprisingly, this period is referred to as "The Fish".

Laccognathus embryi is one fish that was in the top of the food pyramid when it is. These animals can grow 3 meters with a wide head and small eyes. The jaws are very strong fish with big teeth and sharp making it the most terrifying predators.

"I do not want to swim in waters where the fish is stalking prey," said Edward Daeschler of the University of Chicago.

According to him, these fish to find prey in silence in the bottom waters. His eyes are alert to monitor the movement of other fish that pass in the vicinity. When the bite, the jaws are clamped tightly prey animals and lock it with rows of sharp teeth.
