Description:Marine gastropods in Florida are harvested by the marine-life trade, tourists (for shells), and traditional commercial fisheries, but stocks are not formally assessed for most species. The main goal of this project was to estimate biologicalvariables that may be used to evaluate the Species of Greatest Conservation Need status of the banded tulip Cinctura lilium and six other large marine gastropod species that are commonly encountered in the targeted habitats. The principal target, C. lilium , was listed in the 2012 State Wildlife Action Plan. The densities and size structures of C. lilium and six co-occurring species of large marine gastropods in Tampa Bay were examined to evaluate population dynamics, seasonal variation, and habitat preferences ofthese species. Long-term trends in the densities of large, predatory marine gastropods in 10 regions from 2009 to 2017 wereincluded. In Tampa Bay, strong habitat preferences were observed for all species studied: C. lilium andMelongena corona were most likely to be observed on oyster reefs, and Fasciolaria tulipa was found only in seagrass, whereas Strombus alatus ,Triplofusus gigantea ,Sinistrofulgur sinistrum , and Fulguropsis spirata were more common on soft sediments.
