The Triangle spider (Hyptiotes paradoxus) is a very odd spider. Its shape and colour makes it almost impossible to see, sitting on a small branch. It is also one of very few spiders without poson glands, and thus cannot inject venom into its prey. It gets its name from the small triangle web it makes. The Triangle spider are part of the family Uloboridae, Cribellate orbweavers or Hackled orbweavers.
