Saccopharynx ampullaceus
Meet the Gulper Eel, a fascinating deep-sea creature with a large mouth that can swallow prey much bigger than itself. It lives in the darkest parts of the ocean, using bioluminescence to attract food.
Habitat: Deep Sea
The Gulper Eel has an enormous, loosely hinged mouth and a long, slender body that tapers to a whip-like tail. Its small, beady eyes sit high on its head, and its skin is typically dark, often black or brownish-black, blending into the deep-sea gloom.
