Xenoslontus quadrambiguus

From OurFoodChain

After the extinction of C. pyrrhosynopsm in zone 22, there became a large influx of O. disrentius and O. disambiguus due to them having no natural predators anymore. Taking full advantage of this, O. quadrambiguus has developed to eat both of those species. It has done this by making its front fins larger, mostly for extra stability in the water. It has also developed a rigid tail fluke which is the main source of its speed. It gets up to 10cm so as to be able to eat their prey more easily. To help it be a more effective predator, it has developed a powerful, larger jaw. Their jaw strength comes from a buildup of muscle, concentrated beneath the front fins that allows the jaw to snap shut with immense pressure. This bite force is used to inflict major damage to their prey. They reproduce in small batches of only 30 eggs, with these eggs being covered in their mucus layer just like their ancestor.
