Molluscs and Crustaceans
MOLLUSCS
The Reserve has no recent studies on these types of animals. As far as molluscs are concerned, various terrestrial species are certainly present, such as keelback slugs (Limacidae), which have no shell, and snails in the Helix genus, the common land snail, and probably also those in the Cepaea genus, with their yellow and brown striped shells, which were once very common. Aquatic species here probably include the limnea (Lymnaeidae), which has a pointed shell.
CRUSTACEANS
In addition to the exotic crayfish described in the section on invasive species, other tiny aquatic species are present, including copepods, gammarids, water fleas, and others that are often used to study water quality. All are fundamental species for the health of the ecosystem since they form an indispensable link in the food chain. Their scarcity automatically leads to a reduction in fish and birds.
