Slime swapping. Head swinging. Biting. Banana slug mating is INTENSE. https://youtu.be/1VGBy04nIjA

We got up close and personal with banana slug mating so you don't have to. (But you're going to want to.) 🍌

Check out our latest episode if you’re curious about how banana slugs get their -freak- procreation down.

Being a roly poly mom means carrying dozens of babies at once — all protected inside a pouch until they’re ready for the outside world.

It’s an unexpected strategy for such a small, familiar creature.

See how it works in our latest episode, freshly spawned! https://youtu.be/pmLHg_B8uoI

It may look like a simple backyard bug, but the roly poly is anything but ordinary.

These tiny crustaceans (yes, they’re related to shrimp and lobsters) carry their eggs in a fluid-filled pouch, where dozens of babies develop before entering the world.

Watch how this ancient ocean adaptation made its way onto land in our latest episode, out tomorrow.

It curls into a perfect ball when it’s scared — and you’ve probably seen it in your backyard.

This tiny crustacean has something in common with kangaroos. And no, it’s not getting in occasional fist fights with humans.

To find out how roly polies carry their babies, and why it’s one of the strangest parenting strategies in nature, stay tuned for our newest episode, out Tuesday.

And to you as well, spotted lanternfly… We know you don’t mean to be a pest (even though you are!) https://youtu.be/IGtbHRPcSe8

These bugs don’t have to fly far at all — in fact, they hitchhike! https://youtu.be/IGtbHRPcSe8

Spotted lanternflies spread by clinging to cars, shipping containers… even outdoor furniture.

Watch how they got here — and why they’re so hard to stop.

And maybe next time you take a road trip, check your ride for any uninvited passengers!

These bugs don’t just show up… they take over.

Spotted lanternflies are spreading across the U.S. — damaging crops, trees and entire ecosystems.

New Deep Look drops tomorrow. Keep your eyes peeled… and your plants close!

So… what is this thing? 👀

It looks like it belongs at a party — but it’s actually one of the fastest-spreading invasive insects in the U.S.

To find out more about the spotted lanternfly, who wreaks havoc as much as it stuns with its patterned body, stay tuned for our newest video, out Tuesday.
