Anglers have huge mouths and are about as ugly as they come. They have the ability to swallow big fish whole with their massive mouths. Though not popular for their looks, people tend to change their mind after tasting them.
Additionally, Fishers of Iliya Island think it's a lucky omen to find another fish in the stomach of an Angler after it is cut open.
Angler Fish can be caught from various fishing locations throughout the game.
