Northern Rock Barnacle - Semibalanus balanoides

Common, intertidal barnacles that resemble volcanoes or dragon eyes. This rock had multiple generations as you can see from the variations in size.

They have a membranous base and the outer shell consists of white, overlapping, shell-like plates that grow with the animal.

Habitat: Encrusted on rocks in the low tide zone
