It's typical for us to see the x-rays of humans and pets. But have you ever wondered what you would see inside zoo animals?

Lucky for us, curious people, the ZSL London Zoo decided to release these images. These x-rays were taken during the regular check-up of the zoo animals.

According to Heather Macintosh, a veterinary nurse at the zoo, they can detect many things about an animal's health by looking at the x-rays. The team surveyed snakes, turtles, geckos, and armadillos.

Macintosh particularly liked observing the snakes on x-ray. The 200 to 400 vertebrae of these creatures are such a captivating sight.
