By weight · Order from lightest to heaviest.

1. 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.

2. A AA alkaline battery 24 g

   Billions of AA cells are produced worldwide every year, making it the planet's most popular battery size.

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. An adult male sperm whale 45 t

   Its clicks reach about 230 decibels — the loudest animal sound on Earth — and a third of its body is one giant sonar-focusing nose.

6. A Nimitz-class aircraft carrier 100K t

   A floating city of about 5,000 people, it can sail more than 20 years between refuelings of its nuclear reactors.
