By weight · Order from lightest to heaviest.

1. 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.

2. A brilliant-cut one-carat diamond 200 mg

   The carat unit comes from carob seeds, which ancient gem traders used as counterweights on their balance scales.

3. An Etruscan shrew, the world's smallest mammal by mass 1.8 g

   Its heart beats up to 1,500 times a minute, and it must eat about twice its body weight in insects every single day.

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. 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. A Saturn V rocket, fully fueled for a Moon launch 3K t

   Apollo crews rode atop a small warship's worth of kerosene, hydrogen, and oxygen — most of it burned within minutes.
