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.
