Description:
This acorn barnacle is sessile and has a rostrum that extends over the neighboring wall plates (known as carinolaterals in Balanus species). The terga tips lack a beak-like shape, and there are sinuous lines of contact between the terga and scuta. The interior base of the shell features numerous centripetal ridges. The scuta display a diagonal line of pits. The inner surfaces of both scuta and terga are black, occasionally visible on the outside as a dark patch, especially in smaller barnacles. The six wall plates are solid and lack downward-pointing fingerlike spines, except in some young specimens. When removed, the base leaves a calcium deposit on the rock. The wall color is usually white or grayish white and may have longitudinal ribs, which are often eroded in larger individuals.
