Alarm Jellyfish; Atolla wyvillei

If you’re about to get eaten by something, your first reaction is to try and get a bigger something to eat the something that wants to eat you, right? No? It wasn’t mine either, but for this awesome jellyfish that is exactly what it does when disturbed. The biolumnescent alarm jellyfish puts on a fascinating light show when disturbed, in an attempt to attract the attention of a larger fish to eat its predator.

You can see a view of the alarm bioluminescence here.
