Hello Jelly
Jelouhellou is generally found floating near the surface of the waters of Zone 5, basking in the warm sun, using the luminescent gasses inside of its mantle to keep afloat. This unique organism has as symbiotic relationship with two other organisms: Anchugearous osone and Stichodactyla filterous. Very similar to its ancestor, its only notable difference is its new relationship with the macroscopic osone.
Gooey osone grows on the outside of its mantle, which both keeps it away from potential predators and maximizes its exposure to sunlight. This forms a slimy, insulative, transparent coating over the mantle, which offers some protection from smaller would-be predators. Jelouhellou uses its tentacles to feed off of the osone growing on its body.
Growing up to 2.5 meters across, jelouhellou blocks the sun during the day, creating a form of shelter for smaller organisms. This sense of security is betrayed when the stinging feathers of the filterous that hangs below its mantle brush against them, keeping them stunned while the jelly and filterous feed upon them.
The jelly's tentacles are not always fully extended, and are kept coiled close the mantle during the day. At night, the tentacles are extended, and their bioluminescent tips attract lure prey towards the jelly, which are likewise stunned and eaten. The jelly's tentacles secrete a toxic substance that slowly and painfully dissolves its prey as it is absorbed by the tentacles, at the same time converting the prey into a form filterous can filter from the water for itself.
Jelouhellou reproduces sexually. A male releases sperm cells into the water, which the female swims through and takes in through her mouth where they are absorbed into the mantle. Its eggs are incubated inside of the warm mantle, and hatch into a free-swimming form that immediately seeks out a small filterous to form a relationship with. The young jellies (about 1-inch in diameter), once attached to a filterous, will begin to inflate and grow over the course of several weeks, eventually becoming buoyant enough to lift the filterous off of the subsrate and up to the surface.
They will continue inflating for several months, with the lower part of the mantle stretching to compensate, powered by a chemical reaction occurring involving the gasses inside. The chemical reaction produces light, which travels through the jelly's tentacles through a means similar to fiber optics.
The attached filterous will often feature longer feathers than normal (depending on the depth of the water) on account of plentiful food it receives as part of its relationship with jelouhellou. As the jelly inflates, the filterous continues to grow, encouraged by the stretching of the mantle.
