By weight · Order from lightest to heaviest.

1. A ruby-throated hummingbird 4 g

   It crosses the Gulf of Mexico nonstop — about 800 km — burning nearly half its body fat in a single 20-hour flight.

2. An adult giant panda 110 kg

   Pandas spend up to 14 hours a day eating bamboo because they digest only about a fifth of what they swallow.

3. An adult male Asian elephant 4 t

   You can tell it from its African cousin by the much smaller ears and the twin domes on its forehead.

4. 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.

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. General Sherman, the giant sequoia in California 1.3K t

   Earth's largest single tree by volume is still growing, adding roughly a good-sized ordinary tree's worth of wood every year.
