Harps and Morums
family Harpidae is best known for its attractive tropical species,
showing a combination of striking colour and elegance of form, with
sculpture resembling the strings of a harp
It is a numerically small family, with less than 40 species, in
three genera. The genus Harpa,
containing the largest and most spectacularly coloured species, occurs
in the Indo-West Pacific and tropical
Harpa species, and probably also Morum species, live in sand and feed on small crabs. The crabs are enveloped by the foot, and held by large quantities of mucus. Saliva containing digestive enzymes is injected into the crab, and partly digested food sucked out by the mollusc. The diet and habitat of Austroharpa are not known.
Only two representatives of the family occur in NSW, one Austroharpa and one Morum; both occur in deep water, and are rare.
