Nautilus with a distinct spiral shell displaying orange and white patterns, isolated on a white background. The shell's intricate spirals contrast with smooth, extended tentacles that protrude from the shell's opening. The nautilus, a marine mollusk belonging to the cephalopod family Nautilidae, features a prominent hood-like structure above its tentacles. Known for its chambered shell, the nautilus uses gas within these chambers for buoyancy control. The shell's symmetry and pattern are characteristic of the living fossil, a creature that has remained relatively unchanged for millions of years.
