Yeh, the teeth break off into the coypus mouth and they then spit the tooth out like a flying chisel, also been known to wait till a terrier gets hold, then they fling there body over the terrier and rape them, because its done in the water the coypu has the upper hand (so to speak), I heard of a bitch that gave birth to the resulting pups but never seen it myself so cant confirm.
hmmmmmmmmmm really?
