As seen in the model, a male anglerfish comes along for the ride. Small and decidedly unalluring, he parasitically attaches himself to his mate's belly.
Dinoflagellates still puzzle us; we know how they glow, but not why. They might have evolved bioluminescence as a way of frightening predators, or to reveal those predators' locations by flashing when touched. Alternatively, their bioluminescence may just be a fancy way of ridding themselves of oxygen radicals (because the chemical reaction requires oxygen). Whatever the answer, they certainly make for a nice holiday in the Bahamas.
The shrimp, like almost all other deep sea creatures, can't see red light, so they rarely see this ingenious predator coming.
