AHD defines ecdysis as "The shedding of an outer integument or layer of skin, as by insects, crustaceans, and snakes; molting."

Then follows with ecdysiast as "A striptease artist. From ecdysis"

Is there a difference between suffix -ist and -iast?
Now, if we could just find an ecdysiast and ask them! I wonder if one is feminine and one is masculine? In that case, send the masculine one to Wordapalooza! Right ladies?!
