Pomacea sp. (Apple Snail).

I was surprised to find several striking pink egg masses on my dock today. They are eggs of an Apple Snail species. Apple snails are larger than most freshwater snails and "can be separated from other freshwater species by their oval shell which has the umbilicus (the axially aligned, hollow, cone-shaped space within the whorls of a coiled mollusc shell) of the shell perforated or broadly open. There are four species of Pomacea in Florida, one of which is native and considered beneficial." The others are considered invasive because of their voracious appetite for plants.

Ventridens demissus (?) (Perforate Dome Snail).
Size: approx. 10-15 mm. Photo: 08/10/11, 10 am.

Northern Florida is home to three dome snail species. Ventridens demissus is often found in leaf litter but also feeds on the leaves and flowers of garden plants. These snails will travel long distances, especially during rainy evenings; during the daytime, they are often inactive clinging to elevated structures.
