| Sumario: | The aim of this research was the description of the taxocoenosis of Prosobranchia and Pulmonata s ubclasses (Gastropoda) associated with the rocky intertidal zone of the Marine Priority Region 32, Guerrero, Mexico. Based on known species richness, we examine the composition of the community based on the representation of families, assess abundance, the geographic distribution of species, estimate descriptive statistics of size, and estimate diversity. Sampling was conducted at 7 sites, the sampling unit was 1 m -2 and the sampling area was 10 m -2 . One hundred and four species of subclass Prosobranchia and 4 species of subclass Pulmonata were identified. Columbellidae and Muricidae families showed higher species richness, mean while family Muricidae was the most abundant. Acanthais triangularis was the most representative species of the study area, and Macrocypraea cervinetta showed the greatest size. Twenty three species were found with broad distribution, 27 taxa with freq uent distribution and 54 taxa with restricted distribution. Twenty eight species were represented by a single organism and 6 speci es with 2 organisms, these species were considered rare and were found in sites whose characteristic wave exposure is low to me dium. Species richness was high and corresponds to that expected in the tropics. |
