The treppok was easily distinguished by the twelve fins that protruded from its body; six from its midsection, six on the creature's tail. The treppok's interlocking bone structure gave it a naturally strong skeleton. The Krikthasi used their skeletons to build their homes. The average treppok measured roughly thirty meters in length.
