Quick answer
Anglerfish feed as carnivores, adjusting with season, age, and what is abundant in Deep ocean, often below 1,000 m. That label is a preferred pattern, not every item an individual might sample.

Anglerfish diet overview
Anglerfish (Lophiiformes) are best summarised as Carnivore. Anatomy and habitat (Deep ocean, often below 1,000 m) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How anglerfish find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Anglerfish role in the food web
As predators or scavengers, anglerfish move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild anglerfish. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
The glowing lure
Deep-sea anglerfish have a modified spine that extends over the mouth and ends in a fleshy, glowing tip. The light is produced by symbiotic bacteria living inside the lure, an example of bioluminescence. By wiggling this lure in the dark, the anglerfish draws curious prey close to its waiting jaws.
Built for the deep
Many anglerfish live in the cold, dark, high-pressure waters of the deep sea, where food is scarce. They have enormous mouths, expandable stomachs, and long, inward-curving teeth that let them swallow prey nearly as large as themselves. Slow metabolisms help them survive long gaps between meals.
