SortStack #1680 — 2031-01-14

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. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

3. A single sesame seed 3 mg

   Sesame is one of humanity's oldest oil crops, domesticated in South Asia more than 3,000 years ago.

4. An adult human brain 1.4 kg

   It is about 2% of your body weight yet burns roughly 20% of your energy — mostly just keeping billions of neurons ready to fire.

5. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

6. A southern elephant seal bull 3 t

   Bulls can outweigh females several times over — among the most extreme size gaps of any mammal — and dive 1,500 m deep.
