Field Notes
It's 12:40 pm, and we are very cold. The clouds are covering the sky, making it colder. And since we’re on the beach, it is even colder than if we were on the mainland.. There is a lot of seaweed. It wasn't that hard to find the sea potato when we stepped on the beach. We found the sea potato immediately. A lot of them. Now that I think about it, that's probably why it's an invasive species and not a non-native species. Surprisingly it was not attached to other seaweed like normally, but dead and washed up. It's still cold outside.

Supporting Evidence

One reason why I think we found the Sea Potato, A.K.A. Colpomenia Peregrina is because as shown in the image above, it has a bulbous shape, as shown on the vital signs I'D sheet, that's one reason why we know it's a sea potato.
Photo of my evidence.
Its coloration is very distinct. It is a dark, musky green, along with some tan colors. It is relatively small. It grows on a vine like strand of seaweed. When it dies, it disconnects and floats around. Most of the sea potatoes will be dead, detached ones, at the top of the beach.

Another reason why it's a sea potato is its size, according to the vital signs ID sheet it's about 1-7 cm in diameter, the one we found was about 3 centimeters in diameter.
