Lophiiformes

Lophiiformes, commonly known as anglerfish, are a diverse group of fish characterized by their unique predatory adaptation—an extendable dorsal fin spine acting as a lure. This lure, often tipped with a bioluminescent bulb, dangles in front of their mouths to attract prey in dark, deep-sea environments. Most species are deep-sea dwellers with large mouths and teeth, enabling them to swallow prey almost as large as themselves. Their unusual appearance and hunting strategy make them fascinating examples of evolutionary adaptation to extreme, low-light habitats.
