Last weekend the fabled Western Flyer came home to Monterey for a brief visit. For anyone who doesn’t recognize the name, the Western Flyer is the boat that Ed Ricketts and John Steinbeck took to the Sea of Cortez in 1940. At the time of the trip she was just…

A celebration of worms
Yesterday, 30 June 2023, was deemed by the National Museum of Natural History to be International Polychaete Day, and the Smithsonian had an entire day of talks and activities for visitors to learn about the marine segmented worms. And you know me: I’m in favor of any event that draws…
Exception to the rule
Ask any marine biology student to list some interesting factoids about barnacles, and one of them should be “Barnacles are benthic and sessile” by which they mean that barnacles live their entire lives glued to a single spot. This definitely describes what it means to be benthic. Barnacles are indeed…
Rock stars
Some organisms, like some people, have a charisma that just can’t be explained. For me, the sea palm (Postelsia palmiformis) has always been one such organism. Maybe part of its charm is the fact that it’s not very common; it lives on rocky outcrops on exposed outer coasts, which aren’t…
Earthwatch 2: Project ASCO
One of the reasons I selected this particular Earthwatch expedition was that it involved studies of both forest and ocean, which are my two favorite ecosystems here at home. I wanted to compare what I’m familiar with to similar habitats on the opposite coast. Regarding the rocky intertidal, I had…
A most unusual sort of snail
One of the many delightful animals in the rocky intertidal is the vermetid snail, Thylacodes squamigerus. Unlike their more typical gastropod relations, the vermetids don’t live in a shell, per se. Instead, they live in a calcareous tube, which forms a loose coil draped over the surface of a rock….
Natural Bridges
Last week we had some of the best low tides of the season, and I was grateful to spend three consecutive mornings in the intertidal. The picture-taking conditions were fantastic when I went to Natural Bridges, and I snapped away like a madwoman. Unfortunately, last week was also finals week,…
When things are just a little too swell
One of the things that I’ve been doing with my Ecology class since almost the very beginning is LiMPETS monitoring in the rocky intertidal. Usually we have a classroom training session before meeting in the field to do the actual work. This year we are teaching the class in a…
Same or different?
Are the two objects in this photo the same or different? The answer to come!
Glow
On this winter solstice, as we anticipate the return of light, I thought I’d write about a different kind of light. Merriam-Webster defines fluorescence as “luminescence that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength and that ceases…
