By weight · Order from lightest to heaviest.

1. An average adult domestic cat 4.2 kg

   Cats purr at frequencies between 25 and 150 Hz — a range some studies suggest can promote bone and tissue healing.

2. A giant Pacific octopus 30 kg

   It can squeeze its entire body through any gap larger than its beak — the only hard part it owns.

3. A capybara, the world's largest rodent 50 kg

   Capybaras are so famously chill that birds, monkeys, and even crocodilians perch and lounge on them like furniture.

4. A classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

5. The steel arch of the Sydney Harbour Bridge 39K t

   The arch rises and falls up to 18 cm with temperature swings; locals affectionately call the bridge 'the Coathanger'.

6. The Great Pyramid of Giza 5.8M t

   Roughly 2.3 million stone blocks were stacked over about 20 years — averaging a block placed every few minutes of every workday.
