Berthella stellata (Risso, 1826)
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 honey with opaque markings and a well defined central white mark, which is variable in shape ranging from an inverted 'T' or 'Y' to more elaborate forms. Several large white marks may be present in adult specimens. A gill is present, visible on the right side of the body under the notum. A large internal shell is present. Mating has been observed in July with juveniles making their appearance in September/October.
Size range: 3-25mm

Specific characteristics: The body colour and the central white 'cross' are distinctive making this species easy to identify.
