Nautilus

The Nautilus, a private research ship, is operated by the Ocean Exploration Trust. The group says its aim is to examine “areas of the ocean that have never been explored before.”

The nautilus is a mollusk that uses jet propulsion to roam the ocean deep.

The octopus and the nautilus are both cephalopods.

He was still prepared to go on collecting all that life could offer, like a chambered nautilus patiently adding new cells to its slowly expanding spiral.
