Bombadir Beetles

Bombadir beetles are a very unique bug. They are bugs with a strange defense mechanism. They are prey, so they need a way to defend themselves.The way they defend themselves is spitting out boiling acid from their bottoms. The acid kills the prey. One of the things that I find strange about this is how the beetle dose not burn themselves.

This is what they look like.

Here is a video talking about their defensive habit.
