Field Notes
This was a fantastic trip out to one of my favorite places to explore - Casco Bay! My friend and I took a quick boat ride from the ramp in Portland, enjoying the scenery of all the islands and little coves, watching all the different types of boats go by, sailboats, motor boats, lobster boats, and ferries. Then we put on our gear and went for a scuba dive. The water was pretty cold so we had wetsuits to keep warm. The water was also cloudy from all the plankton (tiny plants and animals that live in the water) you couldn't see very far underwater, it seemed like we were way down deep, even though it was only 30 feet or so. It really felt like we were exploring a whole new world! Everywhere we looked we saw incredible things....especially SEA STARS! When we got back I did a quick sketch of one next to snail so you can get an idea of how big it was (2-3 inches).

Supporting Evidence
Photo of my evidence.
I found this little beauty on a rock amongst some seaweed. It had the right shape for a blood star, 5 slender, slanky arms, tube feet on the underside, and about 2 to 3 inches in size.

It has the right color and texture for a blood star. It has a gorgeous deep red color on top, with a light tan color underneath. The texture was smooth, not bumpy or spiky. It seemed like it was curling its toes up when I took this picture.

I found it in the right habitat for a blood star, in the subtidal area, in sheltered areas with good hiding spots, not out in the open. Lots of other cool stuff to find hiding there as well, like this fish that came right up to me! Anybody know what kind of fish this is?

Excellent observations! You focused on specific features of this sea star and what distinguishes it from other species.


All I can say is, "Wow!"

This is such a cool observation! It is enough to make me want to learn to swim better and then take a scuba diving class! Definitely on my to do list.

I also want to learn to draw like that. If that is a quick sketch, what does a not quick sketch look like. Oh way. I already saw that in the project back.

Inspirational work, SuperStar. Way to live up to your name!
