Yep, check out that link to see what they look like.
Here's what happens if you get too close....
They are absolutely vicious plants. They have sections like sausages that break off at the slightest touch and are really painful and hard to get off you.
Many times tourists get in trouble with those plants because they don't really understand how easy they get on you.. hence the "jumping" part of the name, it is as if they literally jump off the plant onto you.
If you see these.. walk very very carefully.. lol
I feel lucky we don't have them! as curious as I am I would be worse than the poor guy on that pic, lol.
