Shelommalis

When the nautipede evolved, some malakommalis was forced to adapt to life on the surface. To survive, the malakommalis formed a symbiotic relationship with the nautipedes, evolving int to a new species, shelommalis. Shelommalis evolved the ability to create small air bubbles within itself to help keep its victim buoyant so the nautipede can get to it before it sinks to the sea floor. This adaptation also help the nautipede stay afloat.

When the nautipedes lay eggs, the eggs are coated in spores of shelommalis. The eggs are then eaten by a creature which soon becomes infected. The spores will then grow, infecting the lining of the stomach, and then they enter the blood stream and spread to the organs and skin, killing the creature within four days. Then the eggs of the nautipede hatch after one more week. They spend a few weeks eating the carcass, allowing the shelommalis to reach its final form. Then when the nautipedes shells are completely grown, they leave the carcass, float up to the surface, and reach adult form. Then the whole process starts again. When shelommalis reaches it's final form, they feed of of the waste of nautipedes.
