You might remember this beautiful barnacle from 2016 or 2017. Paraconcavus pacificus reaches its northern limit in Northern California. I first wrote about this species in September 2016 (see the posts called "Unexpected plate appearance" and "P-pac, Part 2"), and I mentioned it again in February 2017 (see "Red-and-white revisited").
We found two of these barnacles washed up on the beach tonight (16 March 2018). We're still interested in other observations of this southern species, so let us know if you encounter any!

Hi Jackie - we found several washed up on Salmon Creek Beach during a Beach Watch survey on March 6. They were scattered from a little south of Salmon Creek to south of the Dunes Boardwalk. They seem to wash up in clusters when they appear and always make me smile when seeing them :-) Hollis
Again, thank you for helping us appreciate what we see on the beach!
We saw five examples of these barnacles today, March 24, around noon (low tide), all within 75 yards south of the mouth of Salmon Creek (none further south; walked from the south beach parking lot to the creek mouth). All on large sand dollars (3 to 3 3/4 inches across) — none on any smaller sand dollars or broken pieces. A couple with clusters of barnacles of different sizes and colors (large, small, pink, white). Have pictures if you would like them.
Hi!
Yes! We'd love to see pictures to document the observation. We're tracking records of this barnacle north of San Francisco, and all records are welcome and useful! You can send pictures to me at naturalhistoryphotos(at)gmail.com
Thanks so much!
Jackie
