By weight · Order from lightest to heaviest.

1. A black garden ant worker 1.5 mg

   Ants can carry 10 to 50 times their own body weight — the square-cube law makes tiny bodies absurdly strong for their size.

2. A ruby-throated hummingbird 4 g

   It crosses the Gulf of Mexico nonstop — about 800 km — burning nearly half its body fat in a single 20-hour flight.

3. A AA alkaline battery 24 g

   Billions of AA cells are produced worldwide every year, making it the planet's most popular battery size.

4. 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.

5. An adult red fox 5.2 kg

   Red foxes may use Earth's magnetic field to aim their famous pouncing dives — they prefer striking toward the northeast.

6. An adult male African bush elephant 6 t

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