I lol'd too.
But now that makes me paranoid if I'm ever at the beach knowing that spiders can have that ability.
It's a cave spider though, as far as I know, there's no type of spider that's going to be digging around in your local beach area lol.
Anyways, I actually want one of these things. I might never be able to hold it, but it's not so ugly, and has a neat behavior.
