And Now, Some Adorable Scenes from the London Zoo's Annual Weigh-In

This post is exactly what it’s billed as: just a bunch of animals stepping onto the scales yesterday at the London Zoo.

According to the BBC:

There are currently 20,166 animals and 698 different species at the zoo.

While statistics are taken during the year, the zoo says it holds the annual weigh-in to ensure measurements are up-to-date and accurate.

“Weight is a particularly important indicator of health, and we can even detect pregnancies through a growing waist line,” ZSL’s zoological manager Mark Habben said.

That means everybody, from the heaviest—Ellish the giraffe, tipping the scales at more than 1,870 pounds—to the lightest—an unnamed, featherweight leaf cutter ant between three and five milligrams.

There’s this Fea’s Flying Frog:
