I came into a random conversation with an acquaintance of mine after he saw my flytraps. He mentioned a cactus that could shoot it's needles at predators if it felt the foes electric pulses if it got to close to it. I kinda don't believe him to be honest, that just seems way to smart of a plant to protect itself and scary if you have kids and they come to close to it. So I just wanted to put it out there to see if such a cactus really does exist or if you guys heard of such a thing :)

Porcupine literally have to hit the target to break it's quills on the the predator, this cactus apparently can do this all from the feeling of the foes electric impulses which then allows it to shoot the quills onto the body.

Not possible, there's no mammal that could do such a thing. It may be possible with plants, but that's still to be decided. Quite frankly the only thing that I can think of that shoots something as a projectile is a human with a gun.

Not sure if I believe the cactus story...
I have seen video of fish spitting water at insects on overhanging plants to knock them into the water.
You have to admit that is a nice evolutionary/learned trick!!
Peace!

Oh wait I just read further and It's not actually real creepy though.

Oh yeah, that's a smart fish. I remember watching them, that's a sweet way of getting a meal.

I would think not, it was just a specific cactus I was talking about, it probably doesn't exist.
