This alien beast is the deep-sea angler. It is most known for two things: 1) its abominable looks and 2) that dangly, bioluminescent appendage that lures unwitting prey into it's gullet. I imagine that most creatures actually die of fright at seeing the beast before the angler's jaws have a chance to snap shut.
Thankfully, they live in the deep sea realm. We only get to see them when our submarines can get some footage, or when tsunamis wash them ashore.
These creatures prove that it is easy to be ugly when you don't have to look at yourself int the mirror.
