Field Notes
I am happy because we are not at school and we are at the beach searching for cool creatures. I see the ocean, hear the waves and smell the salt water. I am surprised we found a bunch of eels and no sea urchins at Harbor Beach in York, Maine.
Supporting Evidence
They have the same features like dark brown purplish colors, and tiny tip of the spiral which was on a study sheet given to us.
It was smooth and its aperture was white like a common periwinkles is. It also did not have a lot of color variation.
The tip on the snail not having ridges like the others and not a rounded tiphelped pick it out from the other snails in the community.

Hey wicked powerful unicorns, Nice observation! Your second evidence photo and foggy site photo are my favorite.
What kind of eggs did you find? And do you think 9 different species is normal for Maine tidepools or not?
Nice job guys.
