- Abstract
Hipponix australis is identified as having a clear preference for the small, up to ∼18 mm, intertidal nassariid Nassarius pauperatus in Princess Royal Harbour, Western Australia, occurring on a mean of 14% of the population. A few other sand-dwelling nassariids and buccinids (Cominella spp.) are secondary hosts. On N. pauperatus, moreover, H. australis is specific in terms of its location, i.e. on the outer lip of the shell, where it occurs as either solitary females or small undifferentiated individuals, or in clusters comprising a large female with between 2-4 smaller males and undifferentiated individuals. H. australis is a protandrous consecutive hermaphrodite, the change in sex occurring at a shell length of ∼6 mm.
