| Exposed Branching Bryozoan |
|
I walked along the edge of Crab Cove last night during a substantial minus tide. When I arriived, about 5:30 PM, it was dark. In a narrow band along the landward edge of the concrete walkway the water pools, among rocks of various sizes. along the seaward edge is trapped a very narrow and shallow line of water; along one part I find a branched bryozoan, exposed but we t enough to possibly be alive. I am searching for hydroids. None will reveal themselves this evening.

Along this narrow band, I was experimenting with the camera. I have a selfie stick that I hope to use for photo transects along the mudflat, but in this darkness I am reluctant to try it. The selfie stick is capricious, depending on the camera app I employ and the settings, so it requires further experimentation before trying this in the field, on the mud. I am wearing my mud boots, but tonight I will not walk out onto the mud; the only other time I did so in these boots, it was also dark, and I got stuck in the mud for a brief time. Neither am I experimenting with the macro attachment lens.
Along the edge is a railing. It is possible to kneel with one knee on the lower rail. Many amphipods and isopods are scudding about, and insects are around. I take some random shots, found a few insects. A large limpet had emerged from a small crevice, where some conspecifics were still ensconced.
