It has a structure known as ampulla (thickening of the aorta anterior) in the pericard cavity. It has a dual respiration system (gill and lung). Cornea operculum that covers the opening of the shell. Colours of the patterns are very variable, from gold, brown etc. to albino. In Spain, the genus that is particularly common is Pomacea (P. insularum, P. caniculata).

Biology 1

Pomacea: mainly nocturnal activity, keeping submerged throughout most of the day in water and vegetation. Not very active at under 18 oC. They feed on all types of plants, even vascular plants. The reproduction rate varies depending on the availability of food and the temperature, but with great productivity, voracity and resistance to adverse conditions.

Habitat 1

Pomacea: calm or still fresh water environments such as swamps, marshes, lakes, rivers and wetlands. The rice fields in the Delta del Ebro natural park are one of the optimum habitats for the development of this species.
