#Biogeodes#also known as Flesh Stones#are organisms that live encased in a rock deep underground. It is thought that they survive for millennia in this stable environment.#Breaking the rock and exposing the creature to outside air invariably kills it#making its study difficult.#Inconclusive genetic studies have suggested biogeodes descend from an ancient clade of sea urchins.#How they arrived underground#how they manage to survive and their method of reproduction remain a complete mystery to science.
