Back in mid-December I collected some urchins at Davenport Landing. Some of these urchins are the parents of the larvae that I’m culturing and observing now. Towards the end of the trip I flipped over some surfgrass (Phyllospadix torreyi) and saw two fish, obviously sculpins, huddled together; they had been hiding in the Phyllospadix and…

Beginnings and leavings
A few days ago I was in the intertidal with my friend Brenna. This most recent low tide series followed on the heels of some magnificently large swells and it was iffy whether or not we’d be able to get out to where we wanted to do some collecting. Our first day we went up…
Simply green
A few days ago I told my friend Brenna that I’d hunt around in the marine lab for a bit of a green alga that she wants to press. I had a pretty good idea of where to look, only the animals I’d seen it on had been removed from the exhibit hall. I asked…
Hope for the future
It has been almost three and a half years since I first documented seastar wasting syndrome (SSWS) in the lab. Since then many stars have died, in the field and in the lab, and more recently some species seem to be making a comeback in the intertidal. This circumstantial evidence may not be reason enough to conclude that…
The hybrids are winning!
Although at this stage it’s a close race. Two and a half weeks ago I spawned sea urchins in the lab, setting up several purple urchin crosses with the hope of re-doing the feeding experiment that I lost this past summer when I was on the DL (that’s Disabled List, for those of you who don’t…
You can’t push a string
Northern California is currently being pummeled by a meteorological phenomenon called an atmospheric river. The storms produced by these “rivers” tend to be warm and can be very wet, such as the Pineapple Express storms that carry atmospheric moisture from Hawai’i to California. The weather station on the roof of our house has recorded 4.26 inches of rain…
Fine distinctions
Sea urchins have long been among my favorite animals. From a purely aesthetic perspective I love them for their spiky exterior that hides a soft squishy interior. I also admire their uncanny and exasperating knack for getting into trouble despite the absence of a brain or centralized nervous system. Have you ever been outsmarted by…
Seashore to forest
I am fortunate to live in a place of great natural beauty. While the Pacific Ocean dominates much of the landscape, we are also partially surrounded by mountains. I grew up in the flatness of the San Joaquin Valley, a couple hours’ drive from both the sea and the Sierra Nevada but not near enough for either…
Return of the natives
When the most recent epidemic of seastar wasting syndrome (SSWS) began back in 2013, the forcipulate stars were the first to succumb. This group includes conspicuous members of intertidal and subtidal habitats, such as: In the past year or so, I’ve noticed P. ochraceus making a comeback at local intertidal sites. At first I was…
Feeding or sex (or both)?
About three weeks ago I collected some mussels from the intertidal, to use both in the lab and in the classroom. A mussel can itself be an entire habitat for many other organisms. Many of the mussels I brought into the lab this last time were heavily encrusted with barnacles and anemones. I wanted to…
