What is the relationship between anglerfish and bioluminescent bacteria?

Anglerfish have a symbiotic relationship with bioluminescent bacteria that reside in the lure on their heads. These bacteria produce light through bioluminescence, which the anglerfish uses to attract prey in the dark depths of the ocean. In return for providing a habitat, the anglerfish supplies the bacteria with nutrients. This mutualistic relationship enhances the anglerfish's hunting success while allowing the bacteria to thrive.
