Acorn Barnacles (Balanus glandula)

These acorn barnacles were everywhere at Cobble Beach. They are sharp and hurt to put your hand on, but they don't bite or sting (thankfully). As you can see, some have been broken off by humans. The texture of hundreds clumped on a rock was quite incredible, and they are literally all over. I didn't see any open barnacles as the only ones we could find were out of the water. Totally cool if you ask me (though totally pesky to boat owners I imagine).
