Purple Barnacle Coral

Megabalanus tintinnabulum is a species of large barnacle in the family Balanidae. It is the type species of the genus. The specific name comes from the Latin tintinnabulum meaning a handbell. Megabalanus tintinnabulum is a large barnacle, barrel shaped or narrowly conical, up to 5 centimetres (2 in) tall and 6.5 cm (2.6 in) in diameter. It is distinguished from other members of the genus by having ungrooved growth ridges on the scutum and by the parietes having no spines or spiny projections. The parietes can be either rough or smooth, and they are sometimes slightly folded. The basal margin of the shell is either straight or slightly sinuous. The colour is a pale shade of reddish or bluish purple, sometimes streaked longitudinally with a darker or lighter shade and sometimes with transverse bands of colour.
