摘要：The community structure of the class Gastropoda in the reef lagoon of Isla Verde, Veracruz, was analyzedin 3 seasons: windy, dry and rainy. The community analysis of gastropods was based on 4 field trips conducted inOctober 2009, April, August and December 2010. The highest value of Shannon index was 2.422 bit/ind, the mostabundant, 472 specimens, bottom was dead coral and the richest, 27 species, season was rainy season of 2010. Thetotal number of records for this location was 111 species of gastropods. With the samplings carried out, the speciesrichness increased 50%, finding a community with a total of 48 species, of which 18 were living representatives. Thehistorical analysis was conducted based on a review of the area specimens deposited in national scientific collections,as well as records of species reported in the literature. Contrasting sampling with historical analysis, we observed adecrease locally critical in the number of species of large sizes and ornamental value, which reflects the urgency torealize and implement a management plan in the area.
