I also found many tiny crabs in the tidal pool. It is about 0.9 inch wide without legs. Its back is dark green, they walk sideways. There are thick strips on the legs with spots. The body of the crab is square shape. I think these little guys are Asian shore crabs (Hemigrapsus sanguineus). They have "bended legs, red sports on claws." It has different colors as I saw at the same tidal pool.

The day started with a trip to Lovells Island but stop mid way to take advantage of the good fishing spot. Our quarry was a massive striper, two flounder, and x.
After fishing we went to the island and studies the shoreline where we found tide pools with beautiful rocks, small crabs, and a lot of barnacle. Remnants of old military installations dotted the island but nature over came it.
Afterwards we found evidence of land snails on a rock that led me to believe birds smashed them. I also think that other campers might have brought adventurous snails with them in their gear.
First came the Silver Hake, a very elegant fish that is also called a whiting. While I am not the best at drawing I think I did a good job on drawing this fish as you can see in my notes below ..especially on those clear fins on the underside of the fish.
Now for notes. I think they were better than my last batch, but could definitely use some work. I re-wrote some of them to organize them better (and because my little notebook got crushed in my bag), so hopefully they're readable.
This page describes our first task - which was to take the boat to the deepest and coolest waters in the harbor (the main shipping channel) and fish! Bruce mentioned that the water is cooler now than it was last year at this time, and that that would likely affect which species we encounter and what we'll find in their stomachs.
I attempted a few drawings of the sea worms we were using for bait as well.
Next I've got some notes on the fish we caught. The first was a black bass that was about 14". I noted that it had 4 fins behind it's head, two on the bottom and one on each side. It had a dorsal fin running from about 1/3 it's length back from it's head down to where the tail narrowed. It had a fin on the bottom just below where the tail narrowed (which i now know is an 'anal' fin), and then it's tail fin.
The first one we caught had a noticeable bump on the top and just behind it's head, which Bruce pointed out as a sign that it was in the process of changing from a female to a male. The eyes looked about 1/3" to me and it had two very small rows of teeth. It's scales were iridescent purple and blue in some areas and overall it had a black and white pattern.
Here are my drawings of the bass and flounder:
When we got to the tide pools at Lovell island, the tide was still fairly low but was making it's way back in. I found my Asian shore crab, periwinkle, and some barnacles, and also picked up some slipper shells. Here are my notes and drawings of the slipper shells:
Two types of barnacle, that I believe are little greys (the small ones) and a northern rock (the larger one with ridges.
And finally here is my Asian shore crab:
And one more picture: this is Charlie, our boat captain cleaning the big striper we caught. when he cut open the belly there was nothing in there - I assume because the unusually cold water is affecting the population of whatever he would normally eat.
