What is the life cycle of a nautilus?

Answer 1

No one has been able to track a nautilus in the wild from hatch to maturity. In fact, no one knows where their eggs are laid in the wild. Captive nautiluses often develop buoyancy and shell formation problems. Only three places have been able to produce fertile nautilus eggs in captivity and no one has been able to raise one to maturity.

We do not know what the life span is or how long it takes a nautilus to reach maturity. We do know that these ancient mollusks drive in the slow lane, especially when compared to their modern cephalopod relatives. Most cephalopods live for about a year and die. Some, like Idiosepius pygmaeus are born, grow, reproduce and die is 80 days or less.

Answer 2

Almost nothing is known about the life cycle of Nautilus in the wild. What is currently known comes from experiments hatching Nautilus in captivity. You can find some basic information here:
