Description:

Description: Zachrysia trinitaria (Pfeiffer, 1858) - Cuban brown snail shell, modern (latest Holocene) The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. This is a Cuban brown snail shell, Zachrysia trinitaria. Cuban brown snails are pulmonates - they are air-breathing land snails. This is an invasive pest species. It is considered potentially harmful to Florida's native plants and animals.
