Abstract

The shell of Nautilus is commonly thought to be fully mature when it has certain characteristics, namely, a white venter, a thickened apertural edge, a black band along the inside of the aperture, a pronounced ocular sinus on each side, a marked thickening of the final septum, and approximation of the final septa (Stenzel, 1964). This chapter will examine and evaluate these and other putative indicators of maturity and will endeavor to show how mature modifications develop in the ontogeny of the animal.
