The first, second, and third of five Urechis caupo that had been discovered in a small stretch of the muddy shore to the bay's main channel. They were extracted from their dens via a clam gun at low tide during mid-day.
The infamous weenie worm! Very cool inkeeper worm that my professor was on the hunt for, we finally found one after a good hour!
The Echiura, or spoon worms, are a small group of marine animals. Once treated as a separate phylum, they are now universally considered to represent derived annelid worms. The Echiura fossilise poorly and the earliest known specimen is from the Upper Carboniferous (called the Pennsylvanian in North America). However, U-shaped fossil burrows that could be Echiuran have been found dating back to the Cambrian.
