Feeding of three species of molluscivorous Conus, C. textile, C. bandanus and C. omaria, was studied in aquaria. Conus spp. are able to kill and remove from the shell prey larger than themselves. Also, Conus swallowed prey with weight up to half that of the predator. Estimates suggest that molluscivorous species of Conus are probably able to swallow prey with a shell volume reaching 85% of that of the predator, depending on the shape of the prey’s body. It is confirmed that the thinning of the inner shell walls in Conus is connected with the ability to swallow voluminous prey. Digestion of prey occurs in both the oesophagus and stomach.
