If it is asked me what are the plants and animals that I saw
today in the harbor, I would say grass, bird and fish. Since it is not a
sufficient answer for the course content, I will try to differentiate them. And
after summer term, they will go back to their classification; grass, bird and
fish.
Firstly, we again tried to understand whether sea level is
rising or falling. We look at the rocks whether they are wet or dry in order to
understand the sea level is rising or falling. There, we saw rockweeds and we had
chance to look closer and we saw that there were water bubbles on the rockweed.
We saw a fish that is approximately
27-28 inches tall. We threw bread to see those fishes. Also, in the same
location we saw cormorants, one of them was black and the other was white. One of
them dived in the water to find food.
Then, we stopped by the aquarium and there was a sea urchin
located at the bottom of the aquarium. It couldn’t be seen clearly because of
glass and the distance but its color was dark, probably purple or black.
After that, we went to the harbor and we observed the
species that we can see on the surface or near surface. Sea lettuce and seaweed
existed almost everywhere we observed. Their color was mostly green, brown or a
mixture of them.
Also we saw white barnacles on the pillars. After sunset,
they open and eat planktons in the water, but under sun light they are tiny
white creatures, I didn’t guess that they were living organisms at all.
We walked along the harbor and we had opportunity to observe
living organisms in different parts of the harbor. In one of those parts, we saw
mussels behind the seaweeds and sea lettuce. They were black and were embedded
to the other organisms, or I saw like in that way.
Finally, I can count skeleton shrimps which surprised me, it
looks like plant but they started to move after we put them on the wharf. They were
tiny creatures and I guess they had a few legs, their color was light yellow. There
were orange parts near those shrimps but I couldn’t understand what it is.
To compare with the previous year’s posts, I can say that
there are very similar results. The reason of it may be the sea level did not
change much from year to year, or there weren’t any extraordinary events that affect
the variety of living organisms in harbor.
