Bryozoans
Below are images of dried specimens of bryozoans on plastic settlement plates. These images were taken under a stereo microscope. Scale bars are missing in these images. Species were keyed out using the Guide to Identification of Marine and Estuarine Invertebrates: Cape Hatteras to the Bay of Fundy (Gosner 1971) and A Practical Guide to the Marine Animals of Northeastern North America (Pollock 1998). A shout out to Megan McCuller for helping me out with some of these identifications. Any additional help would be appreciated with species identification and corrections.
Morphotype A: Electra pilosa (zooid length: 0.43-0.54 mm; width: 0.22-0.25 mm)
Morphotype B: Membranipora membranacea (zooid length: 0.52-0.74 mm; width: 0.20-0.33 mm)
Morphotype C: Conopeum tenuissimum (zooid length: 0.40-0.49 mm; width: 0.24-0.33 mm)
I previously misidentified this species as Einhornia crustulenta.
