Ceratostoma inornatum and Urosalpinx cinerea
Habitat: Found on the lower shore and sublittoral to a depth of about 12 m, feeding especially on oysters.
Description: Ceratostoma inornatum has a narrow and elongated physiology. It is around one inch (2.54cm) long. The radula is the band of teeth that acts as a "drill" to penetrate the shells of oysters.
Origin and Distribution: The Asian oyster drill is native to
Impacts: Urosalpinx cinerea and Ceratostoma inornatum predate on native and commercial oyster beds. They feed by boring through oyster shells. These species can cause a 25% reduction in oyster farm production.
