Growing up to twenty-five meters in length, Phorayzoa live beyond the reefs, out in the open abyss of Ultra Deep Sea. Their gossamer bodies sport hundreds of flowing, threadlike tendrils that ensnare prey that draw too close. Struggling only tangles the prey more, allowing Phorayzoa to drain its life force at its leisure. Its diet of life energy, in addition to its ability to phase through solid stone effortlessly, has revealed it to be a Ghost type. The vast majority of the time, it drifts lazily through the air, carried by the currents of the alien sea.
On rare occasions, Phorayzoa will become much more active. During these periods of heightened activity, it deliberately seeks out more populous areas, usually crystal reefs. Once it reaches a reef, it will swim in a spiral pattern, soaking up the ambient life force of passing creatures and often tangling even more prey in its coils. They also scoop up the souls of the recently-slaughtered meals of other predators, leeching their life energy away and helping them move on to the next world. Though these creatures usually perform this ritual simply to stockpile nutrients, occasionally they will spawn hundreds of thousands of eggs as soon as they return to the abyss. Larval Phorayzoa are the most well-understood plankton of Ultra Deep Sea, providing food to filter-feeding organisms such as Nihilego.
Phorayzoa's head is covered in lights, which they flash on and off in a multitude of patterns and colors to communicate with others of their kind. So far, sixty-eight discrete patterns have been documented, and around twenty have been translated. The translated signals typically relate to spawning behaviors, territorial disputes, the health of the individuals, or whether the speaker has performed a spiral dance within a certain time frame. The more complex patterns have yet to be decoded.
