Not entirely sure of ID, but Hoover notes that in this species the sides of the shell are fused and it can't close. Certainly me bumbling around near it with a camera didn't make it close.

Description

Yesterday (april 7, 2016) I was out working with Matt Unzelman and Brian Meier, two of Thurston Counties finest, on a project in Beaver Creek, at tributary to the Black River. As we were talking about frogs and fish we looked a little harder and realized there was not one, but two species of freshwater mussels within a meter of each other.

Anyway we found at least 2 live western pearlshells (length 50 -70 mm) and 2 live Oregon Floaters (60 - 80mm) and a shell of each species as well. I have attached some images and recorded a little more locality information below. There will be a small footprint of dewatering later this summer and hopefully there will be an opportunity to do a quick count or some temporary relocation of individuals as well.

Location information:Washington, Thurston County, Crossing of Beaver Creek Rd SW and Beaver Creek (Black River Tributary WRIA 23 stream # 0667) .
UTM: E505514.93?, N5193220.74 Zone10N

See images for habitat detail: Incised channel (likely straightened and deepened in the past, Reed canary grass flood plain giving way to Spirea thickets and Doug fir dominated uplands a ~ 100 feet from channel edge. substrate was sand,grave mix with some organics and evidence of past beaver activity.
Mussel found just upstream of culvert in County ROW, but likely common in the uniform channel. Trout and cottus sp observed, likely Coho, Dace, mudminnow, Shiners? as well.

Second photo - Mom handed juvie otter a single mussel to work on so it'd leave her alone for a while. Took it about 10 minutes to open!

Description from Wikipedia

Bivalvia is a class of marine and freshwater molluscs with laterally compressed bodies enclosed by a shell in two hinged parts. Bivalves include clams, oysters, mussels, scallops, and numerous other families of shells. The majority are filter feeders and have no head or radula. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment on the seabed, where they are safe from predation. Others lie on the sea...
