Patterns in seawater - acorn barnacles

Acorn barnacle shells on chair.
The white shells on seaweed that the waves have thrown on the shore, or growing on stones, or even, as in the photo, on a plastic chair, are signs of acorn barnacles (Balanidae). The acorn barnacles are intricate invertebrates in every way. When you find a piece of dried dark seaweed encrusted with acorn barnacles on the shore it is tempting to turn it into a piece of jewellery!
