By weight · Order from lightest to heaviest.

1. A regulation golf ball 46 g

   The dimples — usually 300 to 500 of them — cut drag so effectively that a smooth ball would fly only about half as far.

2. An adult Chihuahua 1.8 kg

   The world's smallest dog breed is named after a Mexican state and descends from the Techichi, a companion dog of the Toltecs.

3. An adult male grizzly bear 270 kg

   Before hibernation a grizzly can pack on more than a kilogram of fat per day, entering the den far heavier than in spring.

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 hippopotamus 1.5 t

   Hippos cannot actually swim — they sink and gallop along the riverbed, surfacing to breathe every few minutes.

6. Howard Hughes' Spruce Goose flying boat 113 t

   It held the record for largest wingspan of any aircraft until 2019, yet flew exactly once, in 1947 — for about 26 seconds.
