Seashellsnapper

The seashellsnapper split from their ancestor the glowsnapper. They arose after their ancestors began adapting to surviving in the Yokto waterways, where there was an abundance of food of their young to eat. Due to the pressures of predators they have compensated by taking sexual dimorphism to the extreme. The males of their species are identical to their ancestor, the only difference is that they are about half as big. The females, on the other hand, are blue and have developed a protective armor. Their shells are twice as big, covering the majority of their bodies, which are used to protect them from predators. To compensate for the lack of mobility, their shells are filled with segmented gas chambers, which are controlled by their respiratory system. They are now able to to hold their breath longer under water, surfacing every six hours, thanks to an adaptation that allows them to keep some form of gills as adults. When they need to eat they doggy paddle over some food and release their gas chambers. Evey mating season the females will attract males by flashing their bio-luminescent spots. Like their ancestors the males grow tail spikes and ridged backs. The males will battle each other by thrashing their tails, clawing, and biting each other. The winning males mates with the female and dies. The female will then protect the eggs in their shells until they hatch. Like their ancestor, the tadpoles look much like their distant ancestor the volox carpotesta luceremundare and are only around 4 cm long.
