Native to South America, the Apple snail was likely introduced to the Southeast United States by way of the aquarium trade. Certain species are established in Florida, Georgia, Texas, and Louisiana, which is of concern as they have the potential to negatively impact wetland and aquatic ecosystems, agricultural crops, and human health – as they can carry parasites. Apple snails can grow to 6 inches high, and are found in freshwater lakes, rivers, streams, ponds, and ditches. Their presence is often indicated by the bright pink egg masses that consist of hundreds, if not thousands of individual eggs.
