The Effect of Aquatic Plant Abundance on Shell Crushing …

Because calcium carbonate is deposited at a constant rate, if snails reduce food intake (e.g. to avoid predators) they also grow more slowly and develop thicker shells, which can be more resistant to crushing , .Calcium carbonate (Carbo 125), derived from crushing aggregates of limestone, was obtained from Carbomin (Turquel, Portugal). The caprylic/capric acid triglyceride (Tegosoft ® CT) (CT), used as the oil phase, was a kind gift from Evonik Industries AG (Essen, Germany).
