I see sculpins all the time in the ocean. I was very surprised to see this little skulpin-looking fish in lake Tahoe and again surprised to learn that there are indeed fresh-water sculpins. So glad to have seen it. About 35 feet deep.
Skittish when approached, immediately tried to hide in a crack between a building and the sidewalk.
Appears to be in the mustard family. Flower clusters on tall stalks growing all over the Cliffside at the coast.
