Collected during a dredge off the back off a fishing boat. The shell was slightly broken when collected but the snail itself remained alive and intact.

This clam was collected during a dredge off the back of a fishing boat. It is unique due to the fact that it contains hemoglobin, which allows it to have red blood.

This colonial tunicate was found surrounding the sea squirt styela clava, which was attached to a buoy off of MBL dock. This particular colonial is a more recent arrival in the area.

This sea squirt was collected from beneath MBL dock. It can be identified due its rough texture and is often called the "rough sea squirt".

Collected using a dredge that ran along the ocean floor while attached to a fishing boat. Identified by its oversized claws that are both longer than its body.

Collected by running a dredge off the back of a fishing boat. It was easily identified by its distinct purple color and noted as a female due to the large number of eggs within it.

This colorful worm was found in a brackish creek. It was collected by sifting shovelfuls of substrate through a screen.

This chiton was found attached to a rock in the shallows of Great Harbor. It was collected near a number of hermit crabs and was partially covered by the sand.

This crab was collected by using a dredge off of a fishing boat. It was pulled up alive and identified as a female due to her wide abdomen.

These lugworm egg sacs were fished from the shallows of Great Pond with a net. They float suspended in the water while at this stage in their life.

This common and invasive shore crabs was found in the intertidal zone at Stony Beach. They were collected by unearthing rocks, which they often hide beneath.

This periwinkle was found suctioned on to a rock just above the shoreline at Stony Beach. It can be identified by the grooves in the body whorl and the spiraling, pointed apex.

Located below the MBL dock attached to a buoy rope along with a variety of sponges and sea squirts.

This mud snail was found partially buried in the sand in the shallows of the marsh at low tide.

This snail can be identified by its delicate and fragile shell that covers its dorsal half. It was collected from muddy sediment found in the shallows of the Little Sippewissett Marsh at low tide.

Collected by scooping several shovelfuls of mud into buckets from the shallow water of the marsh. Later, the sediment settled and was sorted through. These isopods look similar to large ticks.
