Gulper Eel (Eurypharynx pelecanoides): Deep-Sea Predator with Expandable Jaw #209111 (License: Personal Use)

This detailed 19th-century engraving depicts the gulper eel (Eurypharynx pelecanoides), a mesopelagic to bathypelagic species known for its disproportionately large, hinged jaw capable of swallowing prey larger than itself. Its elongated, whip-like tail ends in a bioluminescent organ used to attract prey in near-total darkness. The fine stippling and cross-hatching highlight anatomical features critical for taxonomic study.
