This past Tuesday and Wednesday afternoon I took my marine biology students to the rocky intertidal at Natural Bridges State Beach. We completely lucked out with the weather; the storm system that brought some of the rain that we desperately need had cleared out, leaving calm, clear seas and little wind. Perfect weather for taking students out in the field, in fact.
First of all, we didn’t see any stars. Not that I was looking for them, particularly, but I was keeping an eye out for them and at this time last year I would have seen many Pisaster ochraceus hanging out in the pools and on the rocks. Here are a couple of pictures I took at Natural Bridges in years past:
The stars, when present, are prominent residents of the mid-intertidal zone, where they feed on mussels. But now, alas, there don’t seem to be any. They WILL come back, and it will be interesting to monitor their population recovery.
I enjoy taking students in the field because many of them have never been there before, and it’s always fun looking at a familiar scene with fresh eyes. When everything is new, it is very easy to be excited and enthusiastic, which these students are.
