I was telling my sister about the "pubic hair" I found in my shrimp the other day and she eventually got on the subject of Pistol Shrimp. She saw a documentary on them on the BBC not long ago. When she told me about them, I couldn't believe how they killed their prey.
Here's a short description on Pistol Shrimp and a video clip of the show she saw on this odd marine creature:
Pistol Shrimp have one (Or sometimes two) oversized claw that create a cavitation bubble as it snaps shut. This bubble, very briefly reaches temperatures approaching that of the sun, about 4700 degrees Celsius. An incredibly loud "popping" noise is created, as well. The Pistol Shrimp is officially the loudest creature on Earth. The bubble they create stuns the shrimp's prey and allows the Pistol Shrimp to eat them.
