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. An adult male western lowland gorilla 160 kg

   Silverbacks are several times stronger than a fit human, yet they eat almost nothing but plants and the occasional termite.

3. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

4. An adult male orca 5 t

   Orcas are actually the largest species of dolphin, and each pod hunts with dialects and techniques passed down like culture.

5. A fully loaded 18-wheeler semi-truck 36 t

   Fully loaded, a semi needs about 40% more stopping distance than a car — which is why truckers leave that gap you keep filling.

6. The supertanker Seawise Giant, fully loaded 650K t

   The longest ship ever built could not transit the Suez or Panama canals — or even the English Channel — when fully laden.
