1. The predation and ingestion rate of Thais haemastoma on oyster spat is sensitive to temperature and salinity. The effect of salinity on predation rate was different at 20° and 30° C.2. The temperature threshold for predation was between 10° and 12.5° C; drills were not observed to feed below 7.5‰.3.

The morphology of the osphradium of Thais haemastoma canaliculata (Gray) was examined using light microscopy, SEM, and TEM. The osphradium is composed of approximately 150-200 lamellae, each of which is divided into two distinct regions by a groove situated parallel to the dorsal edge of the organ.
