| Popis: | The distribution, abundance and morphology of four gastropod species are analized for Dzilam de Bravo, Yucatan, Mexico. Samples were taken by a snorkeler from 1 00 x 300 m plots (31 plots in a 930 000 m2 area) between august and september 1 994. 896 individuals were examined and the more abundant species were Strombus costatus (44.42 %), Turbinella anguláta (42.75 %), Busycon contrarium (5.47 %) and Pleuroploca gigantea (3.46 %). Fasciolaria tulipa and Vasum muricatum represented 3.9 % oC individuals. We estimated a mean oC 0.00096 individuals/m2• The mean shell length oC S. costatus was 182 mm (SD:t20;N 398), T. angulata 232 mm (SD:t52; n=383), B. contrarium 175 mm (SD±48; n=49), and P. gigantea 377 mm (SD±55; n=3 l ). |
