Zygodact
Zygodacts are a bizarre race of Underdark-dwelling creatures native to the worlds of Dungeons & Dragons. Created in issue #267 of Dragon Magazine, they were one of three Underdark PC races created for that issue, alongside the Diopsid and the Sapromneme, and are without a doubt the weirdest of the bunch.
And considering their counterparts are stalk-eyed beetle-people and floating jellyfish-brain fungus creatures with the memories of dead people, that's saying something.
To try and put it simply, a zygodact looks like a man-sized turtle, standing upright on digitigrade, insectoid legs, but with no opening for a turtle's neck. Instead, the turtle's forelimbs are replaced with long round tentacles, tipped in appendages that are simultaneously six-fingered, radial symmetrical hands and functioning heads; each hand sports two eye-stalks where the ring and middle fingers should be, as well as a circular, fang-filled, lamprey-like mouth in the center of the palm. Yeah... these guys aren't your typical demihumans.
