Summary This is basically a roly-poly by the sea. This is basically a roly-poly by the sea. It is most often found by turning over pieces of wood in estuaries in the higher intertidal. This species has the ability to roll into a ball, and to withstand long exposures to freshwater intrusion. [[Ligia pallasi|Rock Louse (''Ligia pallasi'')]] is much larger and flatter, and runs fast. A look-alike species is [[Gnorimosphaeroma insulare|Brackish Water Pillbug (''Gnorimosphaeroma insulare'')]], which looks just the same as the Oregon pillbug, except that it is even more freshwater-tolerant, and when inspected closely, the segments go as follow: from rear to front, the rear-most segment is broad, and is followed by a segment with two creases and three extensions. That creased segment is the important one; in ''G.oregonensis'' all three extensions reach out to the edges, whereas in ''G. insulare'' the rear-most one tapers off just before reaching the edges. If you want to dabble in isopod taxonomy, there is a third species! Its name is ''[[Gnorimosphaeroma noblei]]''. It may or may not be found in our area, and its antennae meet directly, without a rostrum in between them.rectly, without a rostrum in between them.  +
