In biology, it is often the exceptions to the rules we teach that are the most interesting organisms. For example, every child knows that the sky is blue and the grass is green. With a few leading questions you can get a child to generalize that all plants are green. We all know this, right?…

Gulls
Earlier this week I accidentally came upon a baby bird. I was on my way out to the cliff at the marine lab to dispose of a corpse (a fish that died of natural causes) when I noticed a western gull perched on the fence railing and allowing me to get unusually close. It was…
Snow in July
The Sierra snowpack is California’s largest single reservoir of fresh water, accounting for 1/3 of the state’s water supply1. A state with a mediterranean climate, such as California, receives precipitation only during the short rain/snow season. During years of drought, when the average Californian frets about how little rain is falling, state water managers are…
Puzzling
The marine macroalgae are, as a group, the most conspicuous organisms in the intertidal. Yet, most tidepool explorers dismiss them as “seaweeds” and move on to the next thing, which they hope is somehow more interesting. This is akin to visiting the jungles of Brazil and not paying attention to the lush foliage that defines…
Now you see it, now you don’t
This morning in the intertidal I was reminded of how often I encounter animals I wasn’t looking for and almost missed seeing at all. That got me thinking about color and pattern in the intertidal, and how they can be used either to be seen or to avoid being seen. Some critters–the nudibranchs immediately come…
When big is small, and small is big
As far as animal sizes go, we Homo sapiens are rather on the large side of things. While it’s true that many animals are larger than us (we can conveniently lump these animals in the category of ‘charismatic megafuauna’), the truth of the matter is that most animals are much smaller than us. We tend…
Blitzin’ the intertidal, part 2
The intertidal portion of my participation in Snapshot Cal Coast 2017 is complete. I organized four Bioblitzes, two of which consisted of myself and Brenna and the other two for docents of the Seymour Marine Discovery Center (Tuesday) and the docents of Año Nuevo and Pigeon Point State Parks (Wednesday). The four consecutive days of…
Blitzin’ the intertidal, part 1
This is the second year that the California Academy of Sciences has sponsored Snapshot Cal Coast, a major effort to document and characterize the biodiversity of the California coast. To this end the Academy has organized several Bioblitzes at various sites in northern California, and solicited volunteers to lead their own Blitzes, either as individuals…
A return to normal conditions . . . maybe
If anyone remembers, 2015 was a year of strange weather. The Blob of warm water in the northeast Pacific governed weather patterns throughout California, and we had an unusually warm and sunny summer, with none of the normal fog on the coast. Nature’s air conditioner went on the fritz that year. Since I spent most…
Sexy times in the tidepools
It seems that most years, the Memorial Day weekend brings some of the lowest spring tides of the year, and 2017 certainly fits the bill. I’ve been out for the past two days, heading out just as the sun is starting to rise, and already I’ve seen enough to whet my appetite for more. And with…
