Abstract

Life history studies involve the research and observation of organisms, their traits, and reproductive strategies. These studies are significant in gathering evolutionary and ecological information on target species and their environments. In this study, we present life history data from the perforate dome, Ventridens demissus, a widespread zonitid land snail found from Pennsylvania south to Florida and across the Gulf Coast into Texas. Using populations collected in Seabrook, TX, we present data on internal and external shell morphology, shell strength, reproductive behaviors, and egg size. Additionally, we use metagenomics to analyze gut contents to determine the diet of V. demissus. Our data will contribute directly to gaps in terrestrial gastropod biology by observing and describing life history parameters of the perforate dome.
