13. Gulper Eel (Eurypharynx pelecanoides)
The gulper eel is an eel-like fish with a gigantic, expandable mouth that makes up nearly half its body. Its long, whip-like tail ends in a glowing tip, and its jaw can stretch wide enough to swallow prey bigger than itself. It inhabits the deep ocean at depths of 3,000 to 6,000 feet.
What amazes nature lovers is its “living vacuum cleaner” feeding style. When hungry, it opens its enormous mouth like a parachute, lunges forward, and engulfs anything in its path—fish, shrimp, even other eels—then balloons its stomach to hold the meal. Adults who thought eels were sleek and simple are stunned by this deep-sea monster that can literally eat bigger than its own head.
