Common Monkfish

The common monkfish (Lophius piscatorius), also known as anglerfish or goosefish, is one of the most unusual-looking marine species you might encounter while diving. With its flattened body, enormous mouth, and lure-like appendage, the monkfish is a master of camouflage and ambush. It hides on sandy or muddy seafloors, lying in wait to surprise passing prey. Found in temperate Atlantic waters, particularly off the coasts of Europe and the North Atlantic shelf, monkfish generally inhabit deeper zones, making them more likely to be seen on technical or deep recreational dives. Though not a frequent sight, spotting one resting motionless on the bottom is a memorable experience for any diver.

Their strange, prehistoric appearance and stillness can make them hard to distinguish from the seafloor—but a closer look reveals a fascinating predator with unique adaptations, including a bioluminescent lure used to attract prey in low-light environments. While rarely seen by snorkelers due to their preferred depth, the common monkfish is a highlight for experienced divers who enjoy uncovering the ocean’s more mysterious and lesser-known species.
