Bearded Gulper Eel
The bearded gulper eel is a far larger and more active predator than its relatives, and constantly scans the ocean depths for small fish and crustaceans. It takes its name from its delicate external gills, which provide the oxygen necessary for a life on the move. They become most active at dusk, when smaller denizens of the aphotic zone migrate toward the surface of the ocean to feed in the safety of the night. Bearded gulpers follow these migrations and use their headlight-like photophores to illuminate plankton and shrimp. This proves irresistible to schools of lanternfish, who begin to feast on the glowing morsels. Meanwhile, the bearded gulper approaches with its mouth wide open, scooping up any fish too slow to flee.
