Fucus vesiculosus was FOUNDI am happy because we are on the coast of Maine in a tidepool with a marine biology teacher in our group. It is a beautiful day, sunny and warm, and many people are in the water. I see airplanes, boats, rocks, seaweed, waves, birds, and buoys. I hear waves, gulls, and a plane. I smell the ocean. We were surprised to find a live slipper shell, Crepidula, and a limpet in our quadrat. We also found two invertebrates that we need to identify. They might be sponges, tunicates, or bryzoans. We need to do some more research. We took pictures of these specimens. The seaweed was very slippery, but no one went in the water.
This seaweed has paired vesicles, or air bladders, on either side of its midrib.
This specimen has flat blades that are dichotomously branched.
A midrib is present on each blade.

Thanks, that is always a
Thanks, that is always a great feature to remember to distinguish these two species.

good call - the paired air bladders occur specifically in F. vesiculosus. Also note in your bottom picture the lack of a distinct ridge along the receptacle; a ridge being indicative of F. spiralis. Thanks for helping out!
cool
these look really weird, did they smell bad
