Nautilus (from Latin nautilus 'paper nautilus', from Ancient Greek ναυτίλος nautílos 'little sailor') [3] are the ancient pelagic marine mollusc species of the cephalopod family Nautilidae. This is the sole extant family of the superfamily Nautilaceae and the suborder Nautilina .
Nautilus are unable to easily move across areas deeper than 800 metres, and most of their activity occurs at a depth of 100–300 metres deep. [4] Nautilus can occasionally be found closer to the surface than 100 metres, however, the minimum depth they can reach is determined by factors such as water temperature and season. [4]
The chambered nautilus (Nautilus pompilius), also called the pearly nautilus, is the best-known species of nautilus. The shell, when cut away, reveals a lining of lustrous nacre and displays a nearly perfect equiangular spiral, although it is not a golden spiral. The shell exhibits countershading, being light on the bottom and dark on top. This ...
A marine biologist documented her rescue of a rare paper nautilus, “one of the ocean’s weirdest animals,” as she helped the cephalopod find its way back into deeper waters.Australian marine ...
Empty nautilus shells may drift a considerable distance and have been reported from Japan, India and Africa. Undoubtedly the same applies to the shells of fossil nautiloids, the gas inside the shell keeping it buoyant for some time after the animal's death, allowing the empty shell to be carried some distance from where the animal lived before ...
British adventure drama Nautilus will finally be setting sail. After being commissioned and scrapped by Disney+ in an effort to cut costs, the series has officially been picked up by AMC. The ...
When motionless, Nautilus can only extract 20% of oxygen from the water. [62] The jet velocity in Nautilus is much slower than in coleoids, but less musculature and energy is involved in its production. [75] Jet thrust in cephalopods is controlled primarily by the maximum diameter of the funnel orifice (or, perhaps, the average diameter of the ...
On this day 57 years ago, Nautilus-- the world's first nuclear submarine -- accomplished its first undersea voyage to the North Pole. The submarine boasted huge proportions of 3,180 tons ...
