The Deep Secrets of the Nautilus
SMRTR summary
Ancient nautiloids dominated oceans 485-444 million years ago, but new research reveals their modern descendants have evolved dramatically different lifestyles. Scientists tracking living nautiloids with temperature sensors and analyzing shell isotopes discovered these creatures now live 200 meters deeper in colder waters compared to their extinct relatives, likely using smell rather than vision to hunt in darkness. Their shells have thickened to withstand greater pressure, and surprisingly, they're thriving in current ocean conditions.
