Aside from the shell, what other Mollusc defenses can you name? As a nautilus ages and becomes larger, it grows a new chamber on the outside of its shell into which it moves its internal organs, and the inner chambers are filled with gas to help maintain buoyancy. Most obvious, nautiluses possess the ancestral trait. The shell of the nautilus looks similar to the shells of some snails, but the nautilus is a relative of squids and octopuses. In order to swim, the nautilus draws water into and out of the living chamber and makes use of jet propulsion.When water is inside the chamber, the siphuncle extracts salt from it and diffuses it into the blood. Reaching through the interior of the shell is a tubular structure called the siphuncle. Greenwald, L. and P.D. But the other chambers are also important because the nautilus uses them to control . The chambered nautilus, Nautilus pompilius, is a highly vulnerable species because of its life history characteristics, including low reproductive rates, slow growth, and late maturity. Unlike a snail shell, the nautilus shell is divided into chambers with the animal only occupying the largest, outermost chamber. The remarkable shape of the nautilus is a function of its growth process. While swimming up or down through the water column, the nautilus uses its siphuncle to suck fluid into, or draw it out of, the smaller sealed chambers, allowing the animal to adjust its overall buoyancy.
