Answer:
Class Gastropoda
Explanation:
Gastropods are the second largest class of animals (after the Insecta)—with 40,000–90,000 living species and at least 13,000 extant and fossil genera (Ponder and Lindberg, 2020)—and are also one of the most evolutionarily successful groups in the variety of ecosystems and habitats that they occupy. They live in the world’s oceans, freshwater lakes and streams, and terrestrial ecosystems, including deserts, mountains, backyards, and beaches. Their shells range in size from almost a meter to less than a millimeter. Some are algae-eating herbivores, some eat detritus (detritivory), some are parasites, and others are carnivorous predators, including of fish.
