Every year, in June, my big whelk lays eggs. I have a mated pair of Kellettia kellettii living in a big tub at the marine lab. I inherited them from a lab mate many years ago now, and they’ve been nice pets. They’ve lived together forever, and make babies reliably. As June rolls around I…

A new site and a new understanding
I’ve always known staurozoans (Haliclystus ‘sanjuanensis’) from Franklin Point, and it goes to reason that they would be found at other sites in the general vicinity. But I’ve never seen them up the coast at Pigeon Point, just a short distance away. At Franklin Point the staurozoans live in sandy-bottom surge channels where the water…
Fishing in surge channels
This weekend we have some of the loveliest morning low tides of the year, and fortunately the local beaches have been opened up again for locals. The beaches in San Mateo County had been closed for two months, to keep people from gathering during the pandemic. For the first time in over a year I…
Unusual numbers of the usual suspects
Today was the first time I’ve gone out on a low tide since before the whole COVID19 shelter-in-place mandates began. Looking back at my records, which I hadn’t done until today because it was much too depressing, I saw that my last time out was 22 February, when the low tides were in the afternoon….
A different sort of coral
I’m willing to bet that when you think about coral, what comes to mind is something like this: The reef-building corals of the tropics are indeed spectacular structures, incredibly rich in biodiversity and worthy of a visit if you ever get the chance. These coral colonies come in many shapes, as you can see in…
The many faces of anemones
Of course, sea anemones don’t have faces. They do have mouths, though, and since a mouth is usually part of a face, you can sort of imagine what I’m getting at. The sunburst anemone, Anthopleura sola, is one of my favorite intertidal animals to photograph. Of the four species of Anthopleura that we have on…
Tidepooling with visitors
It has been a while since I’ve spent any time in the intertidal. There isn’t really any reason for this, other than a reluctance to venture out in the afternoon wind and have to fight encroaching darkness. There’s also the fact that I much prefer the morning low tides, which we’ll have in the spring….
A world beneath your feet
When we stop to marvel at the wonders of the natural world, we usually forget about all the life that is going on that we don’t get to see. But there is a lot happening in places we forget to look. For example, any soil is an entire ecosystem, containing a variety of small and…
Pescadero
A few weeks ago I was contacted by a woman named Kathleen, who reads this blog and is herself a student of the seaweeds. She said that she studies a site up at Pescadero, about an hour up the coast from me. We decided to meet up during the series of low tides around the…
Boring is anything but
Be honest now. When you think of clams, what comes to mind? If you’re like most people, visions of clams steamed in white wine, garlic, and butter might dance in your head. Or perhaps clams in cioppino or a hearty chowder would be your go-to. In any case, I doubt that clams, as actual living…
