The anglerfish, a deep-sea predator, has a specialized bioluminescent lure called an esca that hangs above its mouth on a modified dorsal spine. In the lightless depths of the ocean, the glowing lure attracts curious or unwary prey towards the anglerfish. When a prey item comes close enough, the anglerfish quickly snaps its large, sharp-toothed jaws to capture and consume the unsuspecting victim.
