Whelk shell. Coloured X-ray of the shell of the whelk,Chicoreus steeriae. The shell with its spines is empty of contents,with the inner chambers and spiral whorls visible. At left is a siphonal canal through which a water current is channelled over the gills. In many whelks this canal has become 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. This species is distributed in the Central Pacific. It is approximately 7.5cm long. Magnification: x1 at 6x7cm size | |
