By weight · Order from lightest to heaviest.

1. A single kernel of corn 300 mg

   Each kernel is botanically a complete fruit, and a typical ear carries an even number of rows — most often sixteen.

2. An adult house mouse 19 g

   Male mice sing ultrasonic courtship songs too high-pitched for humans to hear, with repeated phrases like birdsong.

3. An average newborn human baby 3.4 kg

   Newborns arrive with about 300 bones; many fuse over the years down to the adult count of 206.

4. A Thoroughbred racehorse 570 kg

   At full gallop a racehorse's heart pumps roughly 240 liters of blood per minute — ten times its resting rate.

5. An adult male giraffe 1.2 t

   A giraffe's heart generates about double the blood pressure of most mammals to push blood two meters up its neck to the brain.

6. An M1 Abrams main battle tank 62 t

   Despite the bulk it tops 65 km/h, powered by a jet-style gas turbine engine that can run on almost any fuel.
