Order
Common name: Nautilus
Scientific name: Nautilida
The order Nautilida encompasses the family Nautilidae, which includes the genus Nautilus, known for their distinctive shell with chambers. These ancient cephalopods are living fossils, having remained relatively unchanged for millions of years. In the aquarium, they require specialized care due to their need for cooler temperatures and specific water conditions. They are not commonly kept by hobbyists due to their complex needs and slow reproduction rates. Nautiluses are fascinating for their buoyancy control and unique propulsion method, using jet propulsion by expelling water through a siphon.
