Nautilus
Nautilus pompiliusGreen
In the deep slopes beyond shallow reefs, a nautilus drifts like a living spiral, shell patterned with pale stripes that look drawn by tide and time. It moves by jetting water through a siphon, slow and steady, as if the ocean itself is carrying it.

The animal behind the card
Inside the shell, a chain of chambers holds gas and fluid, letting the animal adjust buoyancy with careful chemistry rather than frantic effort. By night it rises to feed on scavenged bits and small prey, then sinks again toward darker safety when daylight returns.
Because it grows slowly and is drawn to traps, overharvest can empty a place faster than it can recover. The nautilus is an ocean relic that still solves modern physics every day, quietly balancing in a world of pressure and shadows.
Bestiary facts
A nautilus adjusts gas and liquid in its shell chambers to control buoyancy, then moves by jet propulsion.
