The soluble component of the shell matrix acts to inhibit crystallization when in its soluble form, but when it attaches to an insoluble substrate, it permits the nucleation of crystals. By switching from a dissolved to an attached form and back again, the proteins can produce bursts of growth, producing the brick-wall structure of the shell. [2]
Water enters the mantle cavity around the sides of the funnel, and subsequent contraction of the hyponome expands and then contracts, expelling a jet of water. In most cephalopods, such as octopus, squid, and cuttlefish, the hyponome is a muscular tube. The hyponome of the nautilus differs however, in that it is a one-piece flap that is folded ...
