The pallial sinus is an indentation or inward bending in the
mollusk shell's valves that corresponds to the position of the siphons in those types of clams which have siphons (i.e. siphonate). The position of the pallial sinus is often clearly visible as a shiny line on the inside of the bivalve shell.[1][2][3]
