Scythemantis
Everything thus far discovered in the deep sea emits blue or green light except for the dragonfish family. These top predators are among the only deep-sea creatures that can even see red light and use it to communicate with one another; making it suicidal for anything else to evolve it. These guys are the tyrannosaurs of the abyss.

Several shrimp-like crustacea, along with the newly "discovered" Erennid family jelly lines do make use of red bioluminescence and utilize it for communicatory purposes (it is assumed), as well as for the luring of prey—for this reason, it is suggested that perhaps far more species of animals at these bathypelagic depths can cultivate the ability to see red than originally thought, though it is indeed rare. The reason, however, why so few animals make use of the specific color at such depths is that it carries like shit.

so how big are these?
>> Scythemantis
The largest are usually only about a foot long, actually...but only a few fish at those depths grow too large for them to handle.

Yeah I read about the more recent discoveries a while after posting :(

I've always wondered how fast these deep-sea beasties are. Sure, they look like satan's nose hair sprung to life, but do they like just open their mouthes and float into their prey, or do the swim like crazy eels of death to the attack?

That's just creepy. Under water, all in the dark and then having some rough-skinned and tentacly biters jolting around you... Burr.
