Comments:
Rock Barnacle (Balanus balanoides)- Upon first glance, there does not appear to be much more to a barnacle than the outer shell. They are actually quite complex organisms. Barnacles permanently attach their heads to a substrate by a cement that they produce. They have flat, irregular tops and resemble small volcanoes. The outer shell of a northern rock barnacle consists of white overlapping shell-like plates that grow with the animal. A soft cuticle covers the inside of the shell.
