16. Rhino Blitz — Do rhinos need glasses? Although they are prone to outbursts of aggression and are one of the largest land mammals on earth AND have a huge horn on their face, rhinoceroses’ poor vision prevents them from making targeted attacks. I’m not sure if this would hurt their blitzing skills, but who wants to find out? Seriously, if someone doesn’t sack the poachers, the rhinos’ clock will run out soon. The World Wildlife Fund reports that very few rhinos live outside of protected reserves because poachers have hunted them to near-extinction for their horns which some people believe possess magical powers.
