Description
Drupa morum has a thick, globose shell that can reach 5cm with a low spire, large body whorl and flat base that covers the surface of the body as it grows. The shell has a columella with three strong, plicate ridges. The outside layer is white with dark brown nodules, while in the inside appears a dark violet. The aperture is narrow and has conspicuous group of denticles. They are often covered with coralline algae.{{Cite web |title=Mulberry Drupe, Drupa morum |url=https://www.marinelifephotography.com/marine/mollusks/gastropods/drupes/drupa-morum.htm |access-date=2025-04-02 |website=www.marinelifephotography.com}}
Distribution
Drupa morum lives in the subtropical and tropical Indo-Pacific{{Cite web |title=Drupa morum, Purple Pacific drupe |url=https://www.sealifebase.se/country/CountrySpeciesSummary.php?c_code=580&Genus=Drupa&Species=morum |access-date=2025-04-02 |website=www.sealifebase.se}}, including the following locations:
Habitat
Drupa morum inhabits rocky shores and can be found in crevices among the lower eulittoral. It is abundant from shallow waters up to 30 feet deep, typically lives at a sea temperatures of 25-30 degrees Celsius{{Cite web |title=Drupa morum Röding, 1798 - Ocean Biodiversity Information System |url=https://obis.org/taxon/459085 |access-date=2025-04-02 |website=obis.org}} and where the salinity is 30-35 PSU.
Diet
Drupa morum feeds on Eunicid polychaetes and limestone-boring invertebrates in addition to many crustaceans, fishes, sipunculids, and vermetids.{{Cite journal |last=TAYLOR |first=J.
