What fish uses a glowing lure to attract prey in the deep sea?

Did you know that deep-sea creatures have evolved fascinating bioluminescent adaptations to survive in the ocean’s pitch-black depths?

This natural light production is used for various purposes, including attracting prey, communicating, or camouflaging themselves from predators.

For instance, the anglerfish sports a luminous “fishing lure” that dangles from its head to entice unsuspecting prey.

Meanwhile, the vampire squid employs a dazzling light show to confuse and evade predators.

These bioluminescent abilities are not only life-saving for deep-sea inhabitants but also captivate scientists, inspiring research into new technologies for medical and environmental applications.
