The (Flammaedusa), also popularly known as the Jellyfire is the first vertebrate species of cnidarians with nervous system ever discovered. The Jellyfire lives in deep volcanic waters with hydrothermal vents in the south atlantic and the south pacific. Its jelly that origins from head to tail is made of volcanic fluids. It is composed of a more rigid outer layer and a gelatinous, bioluminescent, and highly hot inner layer that has stunning toxins.
When the tail is fully developed, the Jellyfire can reach up to 15 meters long. To keep the tail fully functioning, the Jellyfire uses a lot of energy. Once every six months, it migrates to shallow waters of the Atlantic in kelp forests off the coast of South Africa, where it finds food such as fish, sea lions and even small sharks.
Its survival mechanisms include expanding the tail like a shield, to protect itself from groups of predators and keep them away, and compressing the tail, tapering like a spear, used to pierce prey and injecting paralyzing toxins. In addition, the Jellyfire uses the tail as a bait, resembling a coral and attracting fish to be trapped.
Once the Jellyfire restores its energies, it returns to the deep volcanic waters. When it dies, the jelly completely detaches from her body, evaporating in the water.
