Optional Field Trip 4 - Provincetown

As expected, the Provincetown tidal flat did not fail - we found a plethora of sipunculans (Phascolopsis gouldi), holothurians (Leptosynapta tenuis),  polychaetes of many families (especially the bamboo worm, Clymella torquata), 6 types of bivalves (mainly the quahog, Mercenaria mercenaria) and only 1 gastropod (Littorina sp.). We did not find many nemerteans, or any moon snails, and no live crabs - just washed up lady crabs, Ovalipes ocellatus, and Atlantic rock crabs, Cancer irroratus.

Lecture 5 - Annelida

Our lab will be focused on local polychaetes.

Field Trip 2 - WBNERR, South Cape Beach State Park

On Tues. Sept. 27, we sampled at South Cape Beach State Park in Mashpee. Nancy Church was our guide for this field trip to several habitats within the Waquoit Bay National Estuarine Research Reserve (WBNERR).

Katie's ppt and xls files are attached below as a field trip report.

When the inverts class last visited these sites, we were able to find Leptosynapta (the worm-like holothurian), and we also had a challenge to identify the crustaceans vs. insect larvae in the salt marsh.

Optional Field Trip 1 - Snorkeling at WHOI Pier

Our first optional field trip was to the pier pilings in the small boat well at the WHOI pier and to the MBL pier by Garbage Beach on Weds., Sept. 7, 12:30-13:30.

Thanks to Maya for joining me to sample quickly at the pier before the Oceanus came back in, and then also thanks to Jeanette for being an intrepid new snorkeler in about 2-ft visibility waters!

Please see the attached file for notes on the 7 phyla that we sampled.
