It was quite unfortunate for the viper. no animal is so small.

Last year, a group of scientists in Macedonia made a gruesome discovery on the island of Golem Grad. The 44-acre Golem Grad is home to a wide variety of wildlife, including hundreds of nose-horned vipers. The researchers were conducting a field study of the local wildlife, when they found something terrifying.
One researcher turned over a rock in a clearing to discover a dead female viper with the head of a centipede sticking out of its belly.


Nose-horned vipers are known for regularly going after small mammals, lizards, and birds. Occasionally, they're also known to eat centipedes.

Unfortunately for this particular viper, this centipede did not want to go down without a fight. Judging from the post-mortem examination, it looks like the viper was able to initially eat the centipede. However, once it was swallowed, the centipede tried to claw its way out of the viper's stomach. It nearly succeeded.

The team was able to confirm this story because most of the snake's vital organs were missing when they examined it.

I think the best way to describe this situation is as a turducken of awfulness. After seeing these pictures, I'm getting the overwhelming urge to just stay inside forever.
