Anglerfish, with their menacing gape and dangling lure, are among the most curious inhabitants of the deep ocean. Scientists have hardly ever seen them alive in their natural environment. That's why a new video, captured in the waters around Portugal's Azores islands, has stunned deep-sea biologists. It shows a fist-size female anglerfish, resplendent with bioluminescent lights and elongated whiskerlike structures projecting outward from her body. And if you look closely, she's got a mate: A dwarf male is fused to her underside, essentially acting as a permanent sperm provider.
