If you've ever watched one of those extinct animal shows on Animal Planet (can't remember the one), it showed the largest invertabrate of all time. It was some sort of "Sea Scorpion", however in that episode if I remember right, there was a smaller one they showed that looked very similar to the monster. Then again, it could just be an earwig design.

Found it, it looks much better in the show, give it a watch if you have netflix: http://en.wikipedia.org/wiki/Walking_with_Monsters
