After a short walk and chalk and brief exploration of Fort Warren we were ready to board our private vessel sent by the DCR. Check out the pics I took--

When we finally made it to Lovell's Island we were greeted by on island campers. A beautiful island equipped with camp grounds, Prof Berman was delighted to see people using the island for this use.
Included are pictures of a couple different types of Periwinkles I will try my best to identify.
The bigger shells are smooth and have 3 definite lobes making their characteristics consistent with the common periwinkle. However, the smaller ones are clearly ribbed. The ridges are very clearly defined. It is impossible not to note this difference. Gosner notes that younger periwinkles have ridges and are not as smooth as grown ones. This could explain the difference in texture between the two specimens in the picture. Conversely, these ridged shelled creatures could be a completely different species all together. It is possible that this periwinkle is a Rough periwinkle. Gosner writes that the rough periwinkles typically live on higher ground than the common periwinkle. Given the evidence in this picture, I would hypothesize that these rigged individuals are just young common periwinkles because they are living at the same level as the other common periwinkles.
The other shell i found that appeared different from the thousands of dark periwinkle animals, was this:
This textured white shell stood out from the smooth dark shells. I only found one of these, so I thought it would be worthwhile to take a picture of it. Now I am glad I did! With only cursory research, I guessed that this shel was either a dogwinkle or an oyster drill. Given the size and shape I am more inclined to say that it is a dogwinkle.
Those 3 buys are periwinkles...but the others are land snails and life up in the trees. I believe the empty shells got on the rock by a bird. Birds prey on these snails and they probably bring them and drop them on he rock to crack the shell then eat what's inside. Just an idea, not even a theory.
These are land snails.
