I picked up a Dawn Redwood cone from by a stream, and this amphipod was in it.

Found in the opening of a small water pipe in the night. Shined the flashlight on it. Appeared to run away from the light and head into the dark part of the pipe.

Substrate = red-throated loon

Found on side of tree stump

Black outlines along this shrimp's segments.

Shell is approx 2cm. Keyed it out to A. alternata in Burch, but I'm not confident, as the umbilicus seems too small.
