Resumen
Se analizaron 70 muestras, colectados en las estaciones A (playa lobería),B (Playa Punta Carola),C (Puerto Ochoa)y D (Puerto Chino)en la zona intermareal.Los crustáceos se conservaron en fundas plásticas y en alcohol al 70%. Se Identificó un total de 12 especies,ubicadas así: del Suborden Pleocyemata; Infraórdenes: Caridea con 1 Familia Palaemonidae y 1 especie Palaemon ritteri; Anomura con 3 Familias; Coenobitidae y un ejemplar de Coenobita compressus, Diogenidae con Calcinus explorator, Hippidae con Hippa pacifica; Brachyura con 4 Familias y 8 especies: Familia Mithracidae 1 individuo Mithrax nodosus,Fam. Xanthidae 4 ejemplares Ozius verreauxii, Eriphides hispida,Leptodius cooksoni y Leptodius nodgrassi,Fam.Grapsidae 2 ejemplares Grapsus grapsus y Geograpsus lividus, Fam. Ocypodidae con Ocypode gaudichaudii. Se usó claves taxonómicas para identificar familias, géneros y especies, se sacaran cuadros estadísticas demostrando la variedad y porcentaje de especies e infraórdenes.

They identified a total of 12 species, located as follows: the suborder Pleocyemata; infraorders: Family Palaemonidae Caridea with 1 and 1 species Palaemon ritteri; Anomura with 3 Families; Coenobitidae and a copy of Coenobita compressus, Diogenidae with Calcinus explorator, Hippidae with Hippa pacifica , Brachyura with 4 families and 8 species: Family Mithracidae one individual Mithrax nodosus, Fam 4 issues Ozius Xanthidae verreauxii, Eriphides hispida, and Leptodius cooksoni Leptodius nodgrassi, Fam.Grapsidae 2 units and Geograpsus grapsus Grapsus lividus, Fam Ocypodidae with gaudichaudii Ocypode. Taxonomic keys were used to identify families, genera and species, are taken out statistical tables showing the range and percentage of species and infraorders
