Balanus nubilus Darwin, 1854
Barnacles (Balanidae) are barnacles that belong to the crustacean group. They are sessile animals that cannot change their location in the adult state. Externally visible are only their cones and limbs transformed into barnacles.
The Giant Barnacle of the Northeast Pacific is a filter feeder and feeds mainly on plankton. It has 6 plates. The base of the shell is calcified. The exterior of the barnacle may be heavily eroded or almost completely overgrown by sponges, for example.
It is one of the largest, if not the largest barnacle in the world. It grows to 5-8cm in size, possibly beyond.
Giant barnacles settle on rocks and on pilings from the very low intertidal zone.
