Vicious Volox

The vicious volox split from its ancestor. Unlike its ancestor, it managed to re-evolve its distant ancestor's beak-mouth and spines due to atavism. It uses its beak to snatch its prey and consume it. Another great evolutionary difference between this and its ancestor is that it managed to re-evolve its lungs, which allow it to breath air, along with the water it breaths through its gills, and gives it a greater boost of oxygen that allows it to be a faster hunter than its ancestor and even leap out of the water to snatch blind wingworms. However, only adults have fully functional lungs, while the young have to develop theirs as they grow up. Much like its ancestor, it is able to change colors to attract mates and hide itself from predators, but it also uses its color-changing to ambush its prey. The vicious volox is also territorial, so it uses its glowing spots to keep themselves away from each other as much as possible; otherwise, they bite each other until one of them dies. They lay numerous eggs, but many do not make it due to other predators eating them.
