I came up with an idea for an animal that lives in the deep ocean on another planet. This creature has a body similar to a frilled shark, no eyes, and a large bioluminescent mouth. Its mouth can flash various colors, and uses this to attract prey and scare away predators. I need help coming up with a name for this creature.

How about "Luminodentis"? It combines the idea of bioluminescence (lumin) with the presence of teeth in the mouth (dentis).
