That's just one of those things you see in nature and instinctively know that you probably shouldn't fuck with it.
They have to be poisonous right? I can't imagine anyone going, yes they look just like what my mushrooms risotto needs
I was hiking in New Zealand once, near the ocean, on top of a 200 meter hill, and I saw one of these.
I thought it was an alien at first and it freaked me out. Then I realized it could be a squid that a bird picked out of the water and dropped on the hill.
Then I got home and googled it. Kinda disappointed it wasn't either of those, but it was cool nonetheless. It also smelled foul.
