Project Description

While diving at the base of a rock wall I’ll often see green false-jingle (Pododesmus macrochisma) shell valves on the ocean floor.  The shape of the valves is circular, and the left valve (top) can have radial ridges.  The right valve is translucent with a hole in the middle, through which this animal attaches itself to another larger shell or rock below.  The green false-jingle can grow to 5 inches (13 cm) across, and has a range that includes the Arctic Ocean, Siberia to northern Japan, as well as northern Alaska to northern Mexico.
