Ecological ImpactHerbivory
In Florida canals, M. cornuarietis can consume large quantities of aquatic plants of many genera, including Najas, Myriophyllum, Elodea, Cabomba, and, when abundant, can eliminate rooted vegetation (Hunt 1958; McCann et al. 1996). However, reports of recent damage to Florida ecosystems are lacking (Howells et al. 2006).
