With powerful digestive enzymes, Gulpgalge can swallow nearly anything. When it eats larger prey, its mouth stays open for long enough to leak enzymes into the water, creating a hazard for other Pokémon.

Their poison is strong enough to eat through the hull of a tanker, and they spit it indiscriminately at anything that enters their territory. This Pokémon's stomach fluid can even digest scrap iron.
