The androdioecious barnacle Octolasmis warwickii Gray, 1825 has two types of sexual expression (Yusa et al., 2010): 1) as a hermaphrodite, attached directly to a host crab (mainly of the family
Portunidae), or 2) as a dwarf male, attached to the scutum of a large hermaphrodite, and maturing as male at smaller sizes than the hermaphrodites.
