The only animal—the only organism—that can travel through time in a non-linear fashion is the immortal jellyfish (Turritopsis dohrnii). Turritopsis dohrnii appears to be utterly unique in that it does not age. They are an example of fabled biological immortality, able to revert back to its youngest, polyp state at will. Reversion can happen at any point in its life cycle and may occur indefinitely. It does not decay, and so time ceases to matter to it.

When the jellyfish reverts, does it remember what it was? Does it remember close calls with predators, the impossible vastness of the passing whale? It can’t. It doesn’t have a brain. That’s the whole point. True reversion is only possible without remembering. This is why time travel is restricted to a simpler organism: any animal with a psyche could not stand it.
