Summary
[edit]DescriptionAlytes cisternasii (Iberian midwife toad) (33480216383).jpg | Los machos de sapo partero (género Alytes) son los responsables de esos silbidos a intervalos regulares que tratas de localizar durante horas (sin éxito) cada vez que te alejas de la ciudad para ver una lluvia de estrellas. Siguiendo las llamadas más graves, las hembras localizan a los machos de mayor tamaño y se aparean con ellos. La hembra deposita un rosario de huevos unidos por un filamento que se enreda en las tibias del macho. El macho los fertiliza con su esperma y los carga hasta que los renacuajos están a punto de eclosionar (~1 mes). Aunque estos “padres entregados” podrían haber inspirado aquellas fábulas en las que un sapo húmedo y verrugoso se transforma en príncipe azul, lo cierto es que así los machos se aseguran la paternidad de las hasta 4 hembras diferentes con las que pueden copular cada temporada. |
