Neoplacus xenocytus
After the extinction of several species in zone 2, Tetraplacus cheetoensis started experiencing a shortage of food, slight aggression from electrodontus, and even more intense competition for food. While the presence of new algae did less the pressure on them, some decided to migrate to zone 1.
It continues-to feed on other muscals and algae such as cyanoensis and the various species of other oslontarians. They’ve finally developed another plate, originally a part of their lower jaw plate, on their underbelly which gives their jaw additional freedom of movement.
Due to predation and stress, S. xanthensis have moved into cells within their body and R. electra has done the same so it could exploit the proteins with the cells to inhibit its electricity production so it can reproduce. Because of this, N. xenocytus have developed gigantic cells to house them and fill their needs. These cells are present near their jaw and back, which now has a yellowish coloration due to the xanthensis present. After conception, the 2 species will travel out of the cells to inhabit a hatchlings new body(with R. electra entering a stasis so it can save energy for reproduction).
The offsprings are transparent with a length of about 10centimeters, and spend their time slurping up planktons and photosynthesizing, using the algae within their cells, near the surface of the water. They will develop their plates during adolescence, and as they near adulthood, they will form group with other members of their species with a somewhat organized social structure. Adults can reach up to 1.2-1.4 meters long.
