Jakaslontus bydensis
This species is a derivative of O. angelosis, specifically in zone 12. It is believed that it was a result of accidental cross-breeding between O. angelosis and O. squidyensis, and the result was a split tail similar to squidyensis, however with the split being much farther down on the tail. In addition, the fins of this species also split at the ends to help the species manipulate its positioning in the water more easily. It also grows much larger than other Oslontus do, up to 13cm in length. It lives in zone 5 and consumes any plant matter that resides there, and it has even been seen walking on the islands from time to time, however this species is not capable of efficient land travel, and it is also unable to breathe air. It lays its eggs in the root structures of Plortatus flotatortensis.
