Back in late June, someone kindly alerted me to the presence of some Onchidoris bilamellata over at Doran Beach. I swung by and took a few quick photos. I still need to go back to see if I might be able to get some better pictures, but I thought I'd share this one for now.
Onchidoris is unusual among nudibranchs in that it feeds on barnacles (!). The mottled brown-and-white nudibranch is in the top center of the photo. In the bottom right you can also see a nice chiton (note the shell plates) next to the barnacles.
I wrote about Onchidoris ~8 years ago, so for some more photos and a little more info, check out the post called "The barnacle-eaters" on 24 June 2014.
