Siphuncle: Function, Morphology & Overview

The siphuncle is a strand of tissue passing longitudinally through the shell of a cephalopod mollusc. Only cephalopods with chambered shells have siphuncles, such as the extinct ammonites and belemnites, and the living nautiluses, cuttlefish, and Spirula. In the case of the cuttlefish, the siphuncle is indistinct and connects all the small chambers of…
