Meet Your Invertebrates!

Pisaster ochraceus

Sadly not the most common seastar you will see out there. If you don't know your seastars you may get excited at first seeing the relatively-common Henricia (blood star). Almost all of the Pisaster will be bright purple or reddish. Very occasionally we might find an orange one, those are much more common on the outer coast.
Note that this one is drying out higher up, still waterlogged down low. The deep patterning of ossicles can make these guys hard to pick out at first unless brightly colored; they will typically be somewhere around MLLW, above the Ulva and kelps, crammed into a crevice tightly to shelter from subaerial exposure.


Tigriopus californicus



OK, this is John - I don't know Tigs as well as Morgan does, for sure. But what I learned from her the other day: if you see an anemone in the tide pool, don't bother: copepods are not smart about avoiding the tentacles of an anemone! Look higher up, for the pools that are only occasionally inundated by the sea. They are tiny, and so looking closely for their movement is the key.

Balanus glandula

The grip tape of the intertidal. The barnacle Balanus glandula is here in massive numbers (in part because Pisaster is not), but our big trick will be getting the right barnacle. My 10-cent diagnosis is it has sort of a diamond-shaped operculum (the plates that can open so they feed and mate), and deep shadowed pits on the larger plates; when you pry it up, it has a calcareous basis unlike Semibalanus cariosus, which looks a bit more like a thatched roof construction on the sides. Up high in the intertidal might also have a hard time distinguishing small Balanus from Chthamalus dalli which has a more oval operculum, some diagnostic sutures of the wall plates that I wouldn't expect you to be able to see without very close study and perhaps a hand lens, but they are also a bit more brown in color. Sometimes. Remember, Charles Darwin chose barnacles to study in part because they are SO plastic in morphology, and they almost drove him nuts.


Another key to look at are the sutures in the operculum (4 plates, a tergum and sputum on both sides), Tom Mumford (teaching the marine botany class next door) provided this visual to help:
