Can—or do—spiders eat squirrels? And if they can: What kind of monstrous spider is capable of attacking one? An Australian one? So. Many. Questions.

We wondered these questions after Reddit user _Yodai shared this terrifying photo in Reddit’s WTF community. As you can see, the squirrel carcass is encased in spider silk (shudder).

The user— understandably—didn’t stick around to see what made the web. Of course, we had to investigate. So we called up University of California, Irvine biologist, Bradford Hawkins, to shed some light on this mysterious spider.

Hawkins said that the largest spider in the world—Goliath birdeaters—can eat small birds, but nothing close to squirrel size. These spiders live in South America.

Another large spider—Golden Orb Weavers—will sometimes trap small birds and bats in their strong webs. In fact, Reddit user LowPriorityGangster shared this video of one “sucking the life out of two birds.” Enjoy!

However, the largest web hunting spider in North America—the garden spider—can apparently kill small lizards, says Hawkins. Though they usually feast on insects.

We’re unsure where this picture was taken, but Hawkins has a hunch on its origins: “I think someone is practicing with Photoshop.”

It’s a hoax, he says. “There are no spiders big enough to take on a squirrel.”

You can’t believe everything you see on the web.
