Do nautilus still exist today?
The Nautilus! A beautifully shelled creature you might have heard referred to as a living fossil. Like all cephalopods, these fascinating animals have been around for more than 500 million years! Until recently the nautilus were thought to be rare animals occurring at only a few sites, but are now known to occur throughout most of the tropical Indo-Pacific region.Following the K-Pg extinction event most nautiloid species went extinct, while members of Coleoidea managed to survive. Following the mass extinction, the nautilus became the only extant species of nautiloids.
