Identification
|
| Main identification characters |
| Up to 30 mm in diameter and 30 mm tall, Balanus perforatus is recognised by its tapered, volcano-like shape. The shell wall consists of 6 purplish plates that are often vertically ridged, and sometimes separated at the apex leaving a jagged lip. Inside the operculum aperture, the tissue is marked with bright colours of pink, purple and blue. The tergoscutal flaps are brown to purple in colour, with blue and white spots. |
