Lovells Island- Boston Harbor

This trip was yet another beautiful and exciting trip. We visited Lovell's and Georges Island. Lovell's Island was shaped in a curve life manor. It also had a very diverse wildlife. Another key characteristic for the Island came from its blueberry offerings. It also had many tide pools in which various marine life called home. The water temperature changed from section to section and the water was much more clear than water at the Docks.

The second Island we explored was Georges. We spent much less time on this Island, but in the short span I noticed vastly different characteristics. This island had much more open water. The island seem as more of a recreational place for families. Whiles Georges seemed more suitable for camping expeditions. Georges Island had far more boats and people on the island.

Some of the wildlife I saw throughout the day were:

Asian Shore Crab- eight legs, sandy light brown color, square shape, red spot on claw, gets up to 1inch, often founded under rocks and oysters, intertidal to subtidal zone. (Hitchhikers guide)

Hermit Crab- brownish in color, cocooned in a shell like cover, 1inch in length

Periwinkle- sandy brown in color, two antennas, 3/4 inch in length, had deep whorls in its shell

Tunicate- the tunicate i saw was the orange sheath tunicate. Of course it was orange in color. The texture was of dense circle like pattern.

Grove Snail- This was the land snail. It had four antennas instead of two, and brown in color. The snail had 3 to 4 whorls.

Moon Snail- Is apart of the sea snail category. Often founded in the subtidal zone, and has a darkish gray color.

My observations of this marine life was quite different from that at the barking crab. I think the major difference came with the tidal zones. At Lovell's we were in a subtidal zone, which had alot of open sea that moved back/fourth through the zone. This created a totally new habitat for the marine life. At the barking Crab most of the marine life was found under the dock. While at Lovell's the marine life was found on both land/water and in shelter under rocks/coral. The land snails were different from the marine snails by the habitat of course. Also the land snails had four antennas while the sea snails had two. I think that both these creatures are much alike but over time they just evolved into both land/sea creatures. I believe the snail shells got on the beach near that big rock because previously there was a snail there and they may have been attracted to a specific resource that was only found in that area.
