Overview

Puncturella noachina, common name the diluvian puncturella, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets.

Puncturella noachina faces significant threats from ocean acidification and warming sea temperatures, which affect the species' ability to maintain its calcium carbonate shell structure. Coastal development and pollution further degrade the rocky intertidal and subtidal habitats where this marine gastropod depends for survival.
