Resumen:
Pomacea maculata (Gastropoda:Ampullariidae), also called ?apple snail?, is a freshwater South American species, and is one of the most destructive ampullariid of aquatic crops in its invaded range. Like other species from the Pomacea genus, they deposit their eggs above the waterline on vegetation and rocks in calcareous and brightly colored clutches; coloration is probably a warning signal of their defenses. This remarkable egg-laying strategy exposes the eggs to harsh conditions such as high temperatures, desiccation and terrestrial predators. Among the adaptations to cope with these conditions is the provision of eggs with a perivitelline fluid surrounding embryos that acts as their nutrition and protective source. In the present work we study the composition of P. maculata?s eggs and the neurotoxic activity of the perivitelline fluid and the protein PmPV2.
