Living within M. californianus bed. I. kincaidi?
Living within M. californianus bed. I think it might be Uromunna ubiquita.
Doesn't seem laterally compressed enough to be an amphipod, and it's not like any ispopod I've seen. Something in Munnidae, perhaps? It was very small, maybe 8 mm, and decidedly sluggish. More sluggish than the slugs.
