Before you click away from the page, let me tell you that the cockroach is not that a scary or dirty as you think, says a Taiwanese study. To start with, its eye is an arrangement of around 3,000 lenses and it can smell food over 20 metres away.

It breathes through body holes called spiracles that can be closed with a kind of hairy lid. So, if you flush a roach down the toilet, it doesn't drown; it just shuts off the holes and swims to safety! The best thing it does is eat up your garbage. You don't scream when you see the garbage man just because he works amongst rubbish, right?
