Yes, angler fish do live in the ocean twilight zone, also known as the mesopelagic zone. This part of the ocean lies between about 200 meters (656 feet) and 1,000 meters (3,281 feet) deep, where light begins to fade and the environment becomes darker and colder.
Angler fish are fascinating creatures that have adapted to life in these depths. They are known for their unique adaptation: a bioluminescent lure that hangs from their heads, which they use to attract prey in the dark waters. This adaptation is particularly effective in the dim light of the twilight zone, making angler fish skilled hunters despite the challenging conditions of their habitat.
In addition to their distinctive lure, angler fish have evolved other features that help them survive in the twilight zone, including elongated bodies and large mouths filled with sharp teeth. This allows them to ambush and capture their prey more efficiently.
