A distinctive species of large barnacle with a volcano like form, it is found in the Mediterranean, with South-East England being the Northerly limit of it's range at time of writing. It favours lower shore rocks although it can also sometimes be found on the hull of ships. As with other barnacles, it spends the first stage of it's life as a larvae called a nauplius, before shifting to a form known as a cyprid where it finds a spot to settle where it bonds itself permenantly to it's chosen location. As it grows it will them get bigger.
