Humpback Anglerfish - Melanocetus johnsonii
These anglerfish are found anywhere temperate/tropical where the sea floor is somewhere around 2,000 m/6600ft down, and are considered deep-sea fish. They’re also known as “black seadevils”, from their scientific name. The Humpback Anglerfish are sort of a “standard” anglerfish, in that they’re from the deep sea, the females have the glowing rod protruding from their head, and the males permanently attach themselves to the females as a breeding method.
