Berthella plumula - shell
Berthella plumula (Montagu, 1803)
Medium sized species found under rocks. The general shape is oval to elongated with a foot that is hidden below the notum. The oral veil is flattened and the rhinophores are folded. The overall colour is a pale lemon yellow to orange with net-like markings and occasional short white lines. A gill is present, visible on the right side of the body under the notum. A large internal shell is present. In juvenile specimens the shell covers most of the body.
Size range: 6-25mm

Specific characteristics: The body colour and net-like marking are sufficient characters to separate from related taxa. It may sometimes be confused with B. stellata from which it may be distinguished by the lack of a central white mark.
