By weight · Order from lightest to heaviest.
- 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.
- A standard Good Delivery gold bar, the kind in bank vaults 12.4 kg
Smaller than a brick yet heavier than most pet dogs — gold is so dense this bar would fit in a shoebox with room to spare.
- A full-size kitchen refrigerator 135 kg
Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.
- 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.
- 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.
- A fully equipped fire engine 18 t
Around 2,000 liters of onboard water account for a chunk of the heft — plus ladders, hoses, and hydraulic rescue tools.
