Eric spotted this decorator crab (Pugettia producta) with three species of barnacles attached to it.
Can you find three different species of barnacles?
The red-and-white striped barnacles are Megabalanus californicus.
The next picture includes a view of a second species:
I think the all-white barnacles nestled among the others are Balanus crenatus.
The third species of barnacle has long, flexible "necks." It was attached to several places on or near the crab's legs:
The stalked barnacle is a Gooseneck Barnacle (Pollicipes polymerus).
Three species of barnacle on one crab! We've seen Balanus crenatus on crabs before, but I can't recall finding Pollicipes or Megabalanus on a crab in the intertidal zone on Bodega Head.
It's been an amazing year for Pollicipes settlement — remember that they have a swimming stage that eventually returns to the shore and metamorphoses into a juvenile barnacle. Pollicipes seems to be everywhere and in great abundance. It's probably a good year to find them in unusual places.
Megabalanus is a southern species, so it is rare in general on Bodega Head. Perhaps the warm water of the past year allowed it to do better than usual.
Doing a quick count off the top of my head, there are ~9-10 species of barnacles that live on the rocks or other hard substrates in the intertidal zone on Bodega Head...and ~4-5 species of pelagic barnacles that may wash ashore on local beaches. So that's a total of at least 13-15 species of barnacles that can be found in the Bodega Bay area. These pictures show 3 species at one time. In the past I've photographed 4 species at one time. I think it would be possible to capture 5 species of barnacles in one picture, but it would mean keeping your eyes open for just the right circumstance!
