The Immortal Jellyfish has the unique ability of reversing its development. Jellyfish have eggs and sperm and these get released to be fertilised, then it gets a free-swimming larval form.The larva will move about in the current until it finds a hard surface to mature into polyps, which will then bud off and mature into young jellyfish.The hydrozoan Turritopsis dohrnii (Immortal Jellyfish) is an animal about 4.5 millimetres wide and tall can actually reverse its life cycle.When the jellyfish of this species is physically damaged or experiences stresses such as starvation, instead of dying it shrinks in on itself, reabsorbing its tentacles and losing the ability to swim. It then settles on the seafloor as a blob-like cyst. It has been dubbed the immortal jellyfish as an emblem of transformation. The need to be Lean for a feeling of euphoria and relaxation should be learnt from the jellyfish (Turritopsis dohrnii) which has the ability to transform itself into a younger state to fulfill.
