Fans might be happy to hear that the Thor star is officially on Instagram. And in his first photo posted on Monday, the actor was outside his house on a sunny day when he saw something rather chilling in his grass- a giant serpent.

In the selfie, Hemsworth's eyes are facing towards the enormous snake slithering in the grass. In the caption, he mentioned that his backyard is the "real" Jurassic Park.

Chris Hemsworth Reveals Where He Wants His Kids To Grow Up

It's unclear if the actor's wife, Elsa Pataky, was there when it happened, but since the two have been living in Australia, they probably come across snakes a lot. In fact, she managed to find one right in her house. Luckily, she didn't seem too scared.
