Most of the creatures of the twilight zone are a mystery, as their behavior and habits are unlike any other fish in the ocean.

One of the most fascinating creatures that dwell among these deep waters is the angler fish.

There are approximately 323 species of the angler fish, this article is about a species commonly known as the northern seadevil, and it will tell you everything you need to know about them, including details of their class, order, kingdom, phylum, genus, length, weight, how they search for food, and breeding habits!

The deep-sea anglerfish (Ceratias holboelli) species belongs to the Ceratiidae family. The deep-sea angler fish is found at an incredible depth of 1,300- 6,600 ft (400-2,000 m) below the ocean.

The maximum depth this fish can reach apparently is 14,435 ft (4,400 m)! Its scientific name was given by Henrik Nikolai Krøyer, a Danish zoologist, in 1845.

These ray-finned fishes are commonly known as the long ray seadevil and the northern seadevil. At birth, tiny males have exceptionally well-developed olfactory organs that detect pheromones in the water, so it can from the very beginning carry out its life's purpose i.e.

to find and mate with a female, as encounters can be extremely rare. They are significantly smaller than female angler fish, and finding a female partner is crucial for their survival as their size makes them poor hunters.

Some cannot feed on anything due to their size and need to attach themselves to a female to receive nutrition directly from her. Deep-sea anglerfishes are found in tropical and temperate waters within the Atlantic, Pacific, Arctic, and Indian oceans.
