abstract

  • Cameral water in the shell of the cephalopod Nautilus physically supports each septum while it is being formed; it also provides a reservoir of liquid ballast which is extracted to balance the increase in weight in seawater due to shell and tissue growth. It is not used as an aid to vertical movement. In adults, the sole function of cameral water is ballast in order to maintain Nautilus' slight weight in seawater.
