Atlantic lantern fish (scientific name: Anomalops katoptron, family name: Anomalopidae) is a unique deep-sea luminous fish in tropical and temperate waters of the Atlantic Ocean. It is famous for its unique luminous organs and is called "flashlight in the ocean". It belongs to the family of the order lantern, containing about 5 genera and 20 species, such as the Atlantic lantern fish and the southern lantern fish. It is mainly distributed in the tropical to temperate waters on the east and west sides of the Atlantic, such as the Gulf of Mexico, the Caribbean Sea, the coast of Brazil and the waters of West Africa, and inhabits complex structural areas such as coral reefs, rocks or shipwrecks.

Also known as deep-sea anglerfish or lanternfish, it is a unique fish species that lives in the deep sea. Known for its unique hunting method, it usually has a glowing bait to attract prey. The body structure adapts to the dark environment of the deep sea, and the eyes are relatively small because there is almost no light at such depths. On the contrary, they usually have a glowing organ on their body that attracts small fish or other organisms as food. Large in size, some species can reach a body length of over 1 meter. Rough skin, usually dark brown or black in color, helps them hide in the deep sea. The mouth is large, the teeth are sharp, and it can quickly capture and swallow prey.
