ABSTRACT
The group of Pomacea (Gastropod) mollusks, of sweetwater habitat are widely distributed throughout the American continent; for their life cycle they need a neutral or alkaline pH (≥7) and an optimum temperature of 24ºC. This species presents an olfactory organ denominated osphradium, a yellowish protuberance located below the mantle; this sensory organ is the mollusks' sense of smell. It constitutes the precise means of obtaining chemical information at a distance in their environment, permitting them to discriminate between different substances, which facilitate proper behavior in diverse situations presented during their life cycle. In this research project snails cultivated in captivity in laboratory conditions were used. A histological, ultra-structural and morphometric analysis of the epithelia was made of the osphradium covering. Findings were similar to those of other species of Pomacea.
