A genus of monster from the game [[Final Fantasy XIV]]. 

"The coblyn is a creature of startling appearance that skitters around on its tentacle-like appendages in search of ore. Gridanian scholars claim that a coblyn is an animal that fuses minerals to its body to create a defensive shell. Ul'dahn scholars dispute this theory, stating that these soulkin are, in fact, sentient clumps of geological matter that have adopted biological organs in order to facilitate propagation."
