Pollicipes polymerus
Pollicipes polymerus is a species of stalked barnacle that depend on water motion rather than the movement of their cirri for feeding, and are therefore found only on exposed or moderately exposed coasts. Pics 3-6 show them competing with mussels.
Spotted in tidal pools at low tide at Tongue Point Marine Life Sanctuary.
Pollicipes polymerus is found in the north eastern Pacific Ocean, its range extending from southern Alaska to Baja California. It occurs on rocky coasts in the intertidal zone and favours exposed areas where there is much wave action. It tends to occur in closely associated groups and is often abundant.(Wikipedia)

Thanks again Neil!
These are so cool. I don't ever recall seeing massive clusters of barnacles like these in Australian waters. Lots of other species of barnacle, and heaps of oysters. Once again, colder currents come into play. I love the diversity. Great spotting and pics, Brian.
Thank you so much Sarah!
Here is my spotting of the East Coast (smooth) ones

WOW!!! VERY NICE SPOTTING, Brian!!
I found a few gooseneck barnacles attached to an old backpack that had washed up on the beach at Daytona, FL.
They are FASCINATING!!!!
Thank you very much Tukup.
Cool. I have no knowledge of these organisms at all. Or I should say, I HAD no knowledge. Now I have some. Great fotos and notes. Thanks Brian.
