📖 Overview

Occurs on sandy and muddy bottoms from the coast (below 20 m, Ref. 12382) down to depths of 1,000 m. May also be found on rocky bottoms . It lies half-buried in the sediment waiting for its prey. It attracts prey by means of its fishing filament . Feeds mainly on fishes, occasionally sea-birds. Marketed fresh and frozen; eaten steamed, sautéed, broiled, boiled, fried, microwaved and baked . It is a well-studied species in Europe and is sold without the skin and the head under the name 'queue de Lotte' . Does not adapt well in home aquariums due to its large size .

🐟 Physical Description

Dorsal spines (total): 8; Dorsal soft rays (total): 11 - 12; Anal soft rays: 9 - 10. Peritoneum pale. Head and body depressed. Mouth wide and cavernous. Skin thin and loose, scales absent. Esca bifid, 2 broad, flattened , leaf-like blades. Dorsal spines long, stout and bearing many well-developed tendrils; 4th spine greater than snout width .: short and / or deep; Cross section: flattened.

🌀 Behaviour

Monkfish are ambush predators that lie motionless on the seafloor, perfectly camouflaged against the substrate. They wiggle their illicium (a modified dorsal spine with a fleshy tip) to attract curious fish and invertebrates, which they engulf in a lightning-fast strike. They can consume prey approaching their own size.

🦐 Diet

Monkfish are voracious opportunists feeding on fish (including other monkfish), squid, crustaceans, and even seabirds that land on the water surface nearby. Their enormous gape allows them to consume remarkably large prey.
