Just wanted to share this amazing story of the life history of a deep sea fish. If you find random undirected chance as the creator of all life on earth, think deeper. Angler fish of the order Lophiiformes, primarily inhabit aphotic zones of the ocean. In the light-less abyss these fish rely on the use of large spine containing bio-luminescent bacteria the resemble bait in order to draw prey items toward the fish. Once the lure is contacted by a prey item, the mouth of the fish automatically closes, devouring prey. Further, the stomach and mouths of these fish can be extended up to two times its normal size to allow little discretion toward prey size. Since fish in the abyss are far and few between, mating is carried out through the attachment of male fish to the female. Once the male clamps onto the female, enzymes are released fusing the mouth of the male fish to the female's body. Following this fusion, the male fish slowing degenerates into little more than gonads, providing sperm to the female when necessary. Apparently, the male uses olfactory to locate the female.
