| Los cangrejos "ermitaños" estudiados del género Pagurus (Decapoda: Anomura: Paguridae) son macroinvertebrados del intermareal rocoso marino de la costa central del Perú. Se evaluaron quincenalmente, desde agosto a octubre del 2000 (invierno-primavera) tres especies: Pagurus villosus (Nicolet, 1849), P. edwardsi (Dana, 1852) y P. perlatus (H. Milne Edwards 1848) recolectados en las playas San Francisco (PSF) y Los Enanos (PLE), de la Bahía de Ancón (11° 44,5' LS, 77°6' LW), Lima, Perú, parámetros morfométricos, proporción sexual y de selectividad a conchillas de gasterópodos. Sólo P. perlatus, de PLE, se apartó de la proporción sexual 1:1, representando las hembras un 74,46 %. Los cinco parámetros morfométricos están expresados en mm: longitud del... |

| The description of the embryonic development of the hermit crabs Clibanarius antillensis Stimpson, 1859, C. sclopetarius (Herbst, 1796), C. vittatus (Bosc, 1802), and Pagurus criniticornis (Dana, 1852) and preliminary observations on the development of Pagurus brevidactylus (Stimpson, 1858) and Paguristes tortugae Schmitt, 1933 were done. The analysis of the external morphology of the embryos of the studied species allowed the identification of seven stages: Stage 1, Zygote and cleavage; Stage 2, Homogeneous mass (advanced cleavage and gastrulation); Stage 3, Initiation of the germinal disc (yolk-free area); Stage 4, Percentage of yolk-free area from 5% to 50-70%; Stage 5, Eye pigmentation (comma-shape) and heart beating; Stage 6, Percentage of yolk-free... |

| The reproductive behavior of four intertidal hermit crab species [Clibanarius antillensis Stimpson, 1859, C. sclopetarius (Herbst, 1796), C. vittatus (Bosc, 1802), and Pagurus criniticornis (Dana, 1852)] was studied in São Sebastião Channel, southeastern Brazil. The overall behavior followed previous descriptions for Diogenid and Pagurid hermit crabs but some particular differences were recorded. Male to male agonistic encounters over females and guarding behavior were more common to C. sclopetarius, C. vittatus, and Pagurus criniticornis. During guarding, males clearly grasped females' chelipeds, eyestalks, and the margins of their shell apertures. This oblique guarding and, simultaneously, accessing behavior (OGAP) has never been described for hermit... |
