Part 9: The Shrimp That Vomits Light
Guest Contributor: Dr. Sonke Johnson, Marine Biologist and Deep-sea Explorer

I got some great photos of a bioluminescent deep-sea shrimp called Heterocarpus ensifer. This shrimp spews — aka vomits — bioluminescent fluid.
Think of it sort of like an octopus’ ink. When startled by a predator, it releases a cloud of this glowing stuff. Now, instead of hidden in the dark, the would-be predator is floating, maybe even wearing glowing stuff. If it’s wise, it quickly leaves before an even bigger predator sees it. This gives the shrimp a chance to get away or survive. Pretty smart defense, don’t you think?
Hope you’re enjoying the cruise as much as I am.
