Rhopa

The rhopa replaced its ancestor the opabiron. Now that much of the Ovi water ways have become polar and more salty, they had to adapt to the new climate and salinity. Its 4 eyes have developed into compound eyes so it can better detect prey. Its fins have become bigger for more powerfully swimming. And its had developed a sharp hooked beak with it uses to bite prey and chew iron.

Its reproduction has advanced from "segmentation" to asexual spores. It produces these spores via reproductive organ in its tail. Due to its prey species evolving it new ways it had to adjust its diet. It now has expanded its diet to uktank eggs.
