👉 Haplozetidae is a group of small, aquatic, cephalopod gastropods that are commonly found in freshwater environments, particularly those with a high concentration of planktonic life. These animals have a relatively short lifespan and are typically herbivorous, feeding on algae and other microorganisms. Haplozetidae play an important ecological role as they contribute to the growth and development of aquatic ecosystems by consuming small organisms that support the food chain.
