Field Notes
Low tides were at 11:05 today. We were searching for tunicates along the dock in order to determine how invasive certain species were. We were on the docks around 9 AM.
Supporting Evidence
Photo of my evidence.
This has similar coloration to orange sheath tunicate. The growth was underneath the dock.

This seems to have a large growth on a blue mussel. We found it very close to the dock which is where the tunicate is normally found and it was slimy like is should be.

While is coloration was slightly darker it was once again found on a blue mussel with similar texture and consistency to the others.
