Here we continue our “month of little things” (#NanoLuc) with a deep sea angler fish (though in the video she doesn’t look so little). This female measures a mere 9cm long and uses a bioluminescent fishing lure (modified dorsal fin) to attract unsuspecting prey toward her gaping jaws. This video from the Monterey Bay Aquarium Research Institute is thought to be the first live footage of this species at this depth. Enjoy! In the deep, dark depths of the ocean it’s a little light that makes a difference.
