Field Notes
Our school went to Falmouth Town Landing in search of invasive species. Our invasive species was the Membranipora membranacea otherwise known as the Lacy Crust Bryozoan. We places out quadrat in the same environment that the Lacy Crust is found in. Inside our quadrat we did a thorough search and didn't find any of the Lacy Crust. We then spent about 20 minutes looking around the outer edge of the quadrat, and we think we found our species.
Supporting Evidence
One piece of evidence we have that helps us prove we think we found the lacy crust is because the lacy crust is white or grey, and is a net like or lacy material.

Comments
It's hard to tell if this is
It's hard to tell if this is Membranipora from the picture. The color fits the description of Membranipora, however the texture looks too smooth. It also looks like there are barnacles in the picture, so one possibility is that this is an area where a barnacle used to be attached, and when it died or was pulled off it left behind this white surface that was once part of the barnacle.
