What is the lifespan of a nautilus?
The lifespan of nautiluses may exceed 20 years, which is exceptionally lengthy for a cephalopod, many of whom live less than three even in captivity and under ideal living conditions. Unlike other cephalopods, nautiluses are relatively long-lived, reaching ages of 15 to 20 years, or more. They grow slowly, maturing around 10 to 15 years of age, and produce a small number of eggs that require at least a year-long incubation period.
What is the life expectancy of a Nautilus?
Unlike other cephalopods, nautiluses are relatively long-lived, reaching ages of 15 to 20 years, or more. They are “living fossils”. The first nautilus species appeared over 500 million years ago—hundreds of millions of years before the dinosaurs!
