Boston Harbor Day 3
Day three of our Boston Harbor exploration was a very exciting one. We started the day off by learning about rivers then we walked Boston Harbor canalized river. The water was brackished and flowed in a canal-like manor into the sea. Our first stop was at the Longwarf and Christopher Columbus Park. The water was not clear and had a low tide. The major predators seemed to be sparrows and other birds species. There was a layer of dust/pollen over the water. One species of plant life i saw was a green moss like seaweed. I linked this to being Green algae. It was located on the rocks directly adjacent to the tide. Below this plant was another species of seaweed. It had a black/brownish color. When researching this i found that this brown seaweed belonged to the phaeophyta family.
The second stop along the exploration came at the Harbor towers. The relative difference in this stop and the first stop was the lack of seaweed species previously seen. I think this due the large buildings blocking the sun. I saw a pool of 30-40 fish swimming.
Our next stop came the docks called the Barking Crab. This was the inter title zone. Another plant species i witnessed at the docks was red algae. It was a silky burgundy like plant. It was located in the water under the dock. The first species that i saw that was apart of the animal kingdom was an amphipod. It was brownish/burgundy in color and had multiple legs. The amphipod was about 1 inch. Another species that i saw at the dock was the skeleton shrimp. It was about 1 inch in length and 2 cm in diameter. The color was a light reddish color. I also saw a small fish. It was gray and 1 inch in length. I associated this fish as a baby herring. The other animal species I saw was a small miniature crab. The crab was 1 inch and had a sand like color. The diameter of the crab was 2-3 cm. After looking at the hitchhikers guide I associated this crab as apart of the shore crab family. While at dock I explored an orange daisy like shell creature. The exterior was hard and bumpy. I associated this to a club tunicate.
