By weight · Order from lightest to heaviest.

1. A common housefly 12 mg

   Houseflies beat their wings around 200 times per second, which produces their signature buzzing pitch near the note F.

   Researchers computed this from global census data; North America's average is about 20 kg heavier than Asia's.

3. The Liberty Bell 943 kg

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.

   The largest land animal walks almost silently — its foot pads expand and absorb sound like cushioned trainers.

5. An adult Tyrannosaurus rex 8.5 t

   'Sue', the most complete T. rex ever found, sold at auction in 1997 for $8.4 million and now has its own social media accounts.

6. A Nimitz-class aircraft carrier 100K t
