Anglerfish are a diverse group of marine fish belonging to the order Lophiiformes, characterized by a unique predatory adaptation where a modified dorsal fin spine, known as the illicium, acts as a lure to attract prey. They inhabit a range of oceanic environments, from shallow coastal waters to the deep sea, and exhibit notable sexual dimorphism, particularly among deep-sea species.
Deep-sea creatures are organisms that inhabit the ocean's depths below 200 meters, adapting to extreme conditions such as high pressure, low temperatures, and complete darkness.
