The Light of the Deep Sea: The Anglerfish

At Depths of over 3000 Ft. a master of deep-sea survival- The Anglerfish known for it’s bioluminescent lure, which they use to attract prey This “fishing rod” is a modified dorsal spine that has a light producing organ called the Esca at its tip. Different species have evolved various types of lures. Some resemble worms or small creatures, enhancing their effectiveness in attracting specific types of prey. The light that is produced by the Anglerfish’s lure is due to a symbiotic bacteria that live in the Esca. These Bacteria produce light through a chemical reaction know as bioluminescence. They ambush prey with their large mouths and expandable stomachs capable of swallowing prey twice their size. Females can grow then times larger than males. In Fact, males are so tiny, they attach themselves to females, fusing their bodies together to live off their nutrients. Adapted to harsh deep-sea conditions, they have reduced skeletons and minimal muscles, conserving energy when food is scarce. From its lure to its sharp teeth this is truly one of nature’s most fascinating creatures.
