A pair of Chilean Rose tarantulas were found separately in backyards in northern Britain recently, and people are getting nervous. So what's the big deal about a couple of furry spiders? They spit hairs into people's eyes and blind them.

The man who captured one of the spiders, an inspector for the Royal Society for the Prevention of Cruelty to Animals, told the Telegraph about the tarantula he caught in a woman's garden:

Derek Hampson, an inspector for the animal welfare charity, said: "We advised her to keep it under the plant pot until we arrived. They can quite happily go a week without food, so it was quite content.

"It got a bit aggressive when I picked it up. I wore safety goggles as these creatures can spit hairs which can blind you."

The Chilean Rose tarantula, or Grammostola rosea, can live up to 20 years and grow to be about 10 centimeters wide. And if you mess with them, you could quickly lose your eyesight and be covered in piss:

Before biting or releasing hairs, they will "Musk" the assailant with a mix of urine, feces, and other fluids. This is a foul-smelling mixture. The fluid is ejected from the hind of the spider.

Yeah, that sounds pretty awful. As if losing your vision weren't bad enough, they'll piss and shit all over you, too.
