Description
Summary:Size structure within a population, relative growth of secondary sexual characters in both sexes, and fecundity of females were assessed from field samples of Microphrys bicornutus in the vicinity of Bocas del Toro, Caribbean Sea, Panama. The study was based upon 135 individuals captured by hand and a kick net. Carapace width ranged from 6.5 to 14.4 mm for ovigerous females, 4.2 to 16 mm for non-ovigerous females, and 5.9 to 17.4 mm for males.Original Abstract: Se estudio la estructura de la poblacion, el crecimiento relativo de los caracteres sexuales secundarios de ambos sexos y la fecundidad de las hembras de Microphrys bicornutus de Bocas del Toro, Panama. Se recolecto manualmente y con red un total de 135 individuos. Las hembras ovigeras midieron 6,5-14,4 mm de ancho de caparazon (AC), las no ovigeras 4,2-16 mm, y los machos 5,9-17,4 mm. El crecimiento relativo del largo del caparazon versus el ancho de caparazon fue isometrico en los machos y alometrico negativo en las hembras.
