Northern Rock Barnacle - Semibalanus balanoides This is the crowded form of the northern rock barnacle. When crowded, they take a columnar or twisted shape that can be up to 25 mm long. You can see a bunch of little things attached to this barnacle - mussels, a periwinkle, and smaller barnacles.<br />
<br />
*Note: This barnacle was dead. I wouldn&#039;t have uprooted it otherwise.<br />
<br />
Habitat: Crowded colony in the intertidal<br />
