How would you like to step on this guy with your bare feet in the middle of the night? Luckily I saw him come in the door when I was airing out my apartment. He's a 5 inch long arachnid that looks exactly like a scorpion. He's called a Giant Vinegaroon because he defends himself by squirting acetic acid. By the time I caught him, my whole apartment smelled like vinegar.
