Gave a great response if you live in the us.
Your question sent me on a quest for info ; may have answered a life -long question i had. When i was nine years old in northern taiwan (petou), i picked up a slab rock ; found a humongous centipede. I always wondered if it was poisonous. (kind of like the cone shells i picked up at the beach). Well, i now believe it was a scolopendra multidens.>.
