Gigantopelta aegis is a species of deep-sea snail in the family Peltospiridae, found in hydrothermal vent ecosystems, particularly in the Longqi hydrothermal vent field on the Southwest Indian Ridge. This species is adapted to extreme environments, relying on a symbiotic relationship with chemosynthetic bacteria housed in its gills. These bacteria oxidize sulfur compounds from vent fluids to produce organic matter, providing essential nutrients to the snail. Gigantopelta aegis plays a crucial role in vent ecosystems by contributing to nutrient cycling and supporting microbial and faunal communities.
