Anglerfish are deep-sea fish typically found at depths ranging from about 200 meters (650 feet) to 2,000 meters (around 6,600 feet), with some species inhabiting even deeper abyssal plains between 4,000 and 6,000 meters (2.5 to 3.7 miles) below the ocean surface
. For example, the abyssal humpback anglerfish (Melanocetus johnsonii) is usually found between 200 and 2,000 meters deep but was recently observed near the surface, which is extremely rare
. Most anglerfish live in the dark, cold, and high-pressure environment of the deep ocean, such as the Atlantic and Antarctic oceans, often nearly a mile (about 1,600 meters) below the surface
. In summary, anglerfish inhabit a wide depth range primarily in deep-sea environments from a few hundred meters to several thousand meters deep, adapting to extreme conditions of darkness and pressure in these depths.
