Whelk shell. X-ray of the shell of an unidentified whelk. The shell is empty of contents,with the inner chambers and spiral whorls visible. At centre right is a siphonal canal through which a water current is channelled over the whelks gills. In many whelks this canal bearing a siphon acts as a type of nostril,and it is able to sample and smell substances in the water. In this way many whelks can find their prey or scavenge on dead marine animals | |
