Dear Andrew, This isopod bel
Dear Andrew,
This isopod belongs to the family Ligiidae and genus Ligia. One widely distributed common species is known as Ligia oceanica, but I can't give specific identification from the picture.

Ligia, however, is a group of isopods that live on seashores under permanently humid conditions.
Best wishes, F.

not oceanica
Thanks for the genus identification. Further exploration on the internet reveals that oceanica can be ruled out by range (it is limited to Europe and the US east coast). Ligia pallasii is the only one I can find whose range includes the Pacific Northwest (where it was found).
