A cockroach will live nine days without its head before it starves to death. (Creepy.) Banging your head against a wall uses 150 calories an hour. (Don't try this at home; maybe at work.) The male praying mantis cannot copulate while its head is attached to its body. The female initiates sex by ripping the male's head off. (Honey, I'm home. ) The flea can jump 350 times its body length. It's like a human jumping the length of a football field. The catfish has over 27,000 taste buds. (What could be so tasty on the bottom of a pond?) Some lions mate over 50 times a day. Butterflies taste with their feet. (Something I always wanted to know.) The strongest muscle in the body is the tongue. (Hmmmmmm.......) Right-handed people live, on average, nine years longer than left-handed people. (If you're ambidextrous, do you split the difference?) Elephants are the only animals that cannot jump. (Okay, so that would be a good thing.) A cat's urine glows under a black light. (I wonder how much the government paid to figure that out. An ostrich's eye is bigger than its brain. (I know some people like that.) Starfish have no brains. (I know some people like that, too.) Polar bears are left-handed. (If they switch, they'll live a lot longer.) Humans and dolphins are the only species that have sex for pleasure.
