Learn About Monkfish (Anglerfish of Genus Lophius)
Monkfish, belonging to the genus Lophius, are fascinating benthic predators found in the depths of the ocean. Known for their peculiar appearance and stealthy hunting techniques, these anglerfish have earned nicknames like “sea devils” due to their eerie demeanor.
Fun Fact: Monkfish use a specialized lure, called an esca, on their head to attract unsuspecting prey directly into their large mouths!
Where to Find Monkfish
Monkfish inhabit cold, temperate waters in the Atlantic Ocean and adjacent seas. These bottom-dwelling predators are most commonly found:
On sandy or muddy seabeds, where they camouflage to ambush prey.
At depths ranging from 20 to 1,000 meters, depending on the species.
Ocean Regions:
North Atlantic Ocean.
Mediterranean Sea.
Coastal waters off Europe and North America.
Their habitats are ideal for their predatory lifestyle, providing ample cover and prey.
Famous Dive Sites for Monkfish Encounters
Monkfish are rarely the primary focus of recreational dives but can be spotted in specific cold-water diving locations known for their unique seabed ecosystems:
Norwegian Fjords (Atlantic Ocean):
Best Time: Year-round, but winter offers clearer visibility.
Why It’s Famous: Cold, deep waters provide prime habitats for monkfish and other benthic species.
Silfra Fissure, Iceland (Atlantic Ocean):
Best Time: Summer for calmer waters.
Why It’s Famous: A unique opportunity to encounter benthic species, though monkfish sightings are rare.
Gulf of Maine, USA (Atlantic Ocean):
Best Time: Spring and fall.
Why It’s Famous: Rich ecosystems with diverse bottom-dwelling marine life, including monkfish.
- Il-Kantra, Gozo Malta (Medditerian Sea)
Best Time: Spring and fall.
Why It’s Famous: These fish have a history here since Greek poet Oppian, a 2nd-century Greco-Roman poet coined these Anglerfish as ‘day sleepers’ so these bottom-dwelling monkfish are famous in these waters
How to Identify a Monkfish
What does a Monkfish look like? Here’s a simple checklist to help you identify a Monkfish:
Key Identification Markers:
Flattened body with a wide, round head.
Large mouth filled with sharp, inward-pointing teeth.
Small lure (esca) on the head used to attract prey.
Brown or mottled coloration that blends with seabeds.
Common Misidentifications:
Sometimes confused with other anglerfish, wobbleygongs or flatfish species due to their flattened shape. Unlike flatfish, monkfish have a distinct lure and a more predatory appearance.
Monkfish Characteristics & Behavior
Monkfish are ambush predators with intriguing behaviors and traits:
Feeding Habits: They use their esca to mimic small prey, luring fish and crustaceans close enough to be swallowed whole. Their expansive jaws and elastic stomachs allow them to consume prey nearly as large as themselves.
Habitual Locations / Migration Patterns: Generally sedentary, monkfish remain in one area for extended periods but may migrate to shallower waters for breeding.
Interaction with Other Species:
Prey: Fish, crustaceans, and cephalopods.
Predators: Sharks and large marine mammals occasionally prey on monkfish.
Interaction with Divers: Typically docile, monkfish may remain motionless on the seabed when approached but can quickly dart away if disturbed.
Conservation of Monkfish
Monkfish Species Conservation Status
Lophius piscatorius:
IUCN Status: Least Concern.
Found primarily in the North Atlantic, this species faces threats from overfishing and bycatch due to its high commercial value.
Lophius budegassa:
IUCN Status: Data Deficient.
Found in the Mediterranean and eastern Atlantic, its population trends are unclear, but it shares similar threats to Lophius piscatorius.
Conservation Efforts:
Implementation of fishing quotas and sustainable harvesting practices.
Protection of critical habitats like spawning grounds.
Overall, monkfish are not currently endangered, but continued monitoring and responsible fishing practices are vital.
Photography Tips for Monkfish
Monkfish as Photography Subjects: Despite their unusual looks, monkfish make for fascinating underwater photography subjects, especially for those interested in benthic species.
Tips for Getting the Best Monkfish Shots:
Angles & Composition:
Wide Shots: Capture the monkfish in its camouflaged environment to highlight its stealth.
Close-Ups: Focus on the esca or teeth for dramatic shots.
Lighting:
Natural Light: Use higher ISO and slower shutter speeds in deeper waters.
Backlighting: Adds depth to the image, emphasizing the monkfish’s textures.
Flash: Use a diffuser to avoid harsh reflections on the seabed.
Behavior to Watch for:
Feeding: Try to capture the moment they deploy their lure.
Camouflage: Document their ability to blend into their surroundings.
Eco-friendly Photography Advice:
Avoid disturbing their habitat.
Maintain buoyancy to prevent kicking up sediment.
Recommended Camera Settings
Using Natural Light / White Balance:
Shutter Speed: 1/125 to 1/250 sec.
Aperture (f-stop): f/5.6 to f/8 for a sharp depth of field.
ISO: 400 to 800, adjusting for depth and light conditions.
Using Underwater Strobe Light:
Shutter Speed: 1/250 sec or below your camera’s sync speed.
Aperture (f-stop): f/8 to f/11 for optimal sharpness.
ISO: 200 to 400 to reduce grain.
Bonus Tips for Photographing Monkfish
Most Photogenic Angle: A head-on perspective accentuates their unique facial features and esca.
Rare Photo Opportunities: Capture them mid-feed or deploying their lure.
Filter Suggestions for Videographers: Use a red or magenta filter for balanced colors in deep water.
Interesting Facts About Monkfish
Monkfish are sometimes called “poor man’s lobster” due to their firm, sweet-tasting meat.
Females lay up to 1 million eggs in ribbon-like masses that float on the ocean surface.
Their large mouths allow them to swallow prey nearly half their size.
Did you know? Despite their intimidating appearance, monkfish are a culinary delicacy in many parts of the world!
Dive Seasonality
Monkfish can be seen year-round due to their sedentary nature. However, regional differences in visibility and water conditions may affect your chances:
Best Times: Winter months often offer clearer visibility in colder waters.
Regional Differences: Shallower sightings are more likely during breeding periods.
