These snails were present in large numbers behind the Dune Line. The have been previously identified as Otala lactea, and are said to have been present at this location for almost a Century. I have an issue with this identification, as there are some notable differences between this snail, and typical Otala lactea, First, these snails only seem to grow to about a maximum size of 35mm. Second, the shells are almost alabaster colored, with little variability. The animal is much darker than Otala lactea, and the shell is thinner despite ample sources of calcium. It is my opinion that this is a distinct sub-species of O. lactea, or another member of Otala. I would suspect that only DNA analysis would be able to answer this.
