not only native, but the ONLY place. I've got carnivores from every continent (accept Antarctica, obviously), and thats STILL my favorite fact.

It does make sense they're so rare though. Most carnivory you can picture the evolutionary path: Something had a mutation that kind of made a cup, something had a mutation that kind of made the leaves sticky... etc. You can see it happening one step at a time with minor advantages (and therefore survival) at each step, until they kept compounding into more and more complex and specialized structures.

For a VFT... multiple things had to happen at once. There's no advantage to the motion until you can also digest and adsorb the material. There's also no advantage to a partial motion that can't trap an organism. It's really wild they exist!
