Not to be confused with the Angler NPC.

The Angler Fish is a Hardmode enemy which spawns in the Cavern layer and in the Jungle. It swims faster than Piranhas when chasing the player, and can inflict the Bleeding debuff for 45 / 90 / 112.5 seconds. It has a small glowing bulb sprouting from its head that emits a small amount of light.

Trivia

In reality, the anglerfish lives deep under the sea, and like their game counterpart, the females do have a small glowing bulb they use to attract prey.

The Bestiary entry for the Angler Fish: "Some angler fish are content to lie in wait for their prey, but these are perfectly happy to aggressively chase down an underwater meal."
