Quick answer
Chambered Nautiluss (Nautilus pompilius) are invertebrates found across multiple regions. The living-fossil cephalopod in a spiral shell. Adults typically weigh roughly 1.3 kg (3 lb), reach speeds of Slow; drifts by gentle jet propulsion, and live 15–20 years. They feed on carnivore and scavenger (shrimp, crabs, carrion) and are listed as Least Concern on the IUCN Red List. Deep reef slopes of the tropical Indo-Pacific, from the Andaman Sea to the waters around Australia and Fiji.

Range and habitat
Chambered Nautiluses inhabit Deep reef slopes of the tropical Indo-Pacific, from the Andaman Sea to the waters around Australia and Fiji. Their preferred habitat includes deep reef slopes of the tropical indo-pacific, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-t
Physical characteristics and behaviour
Adult chambered nautiluses typically measure about 0.25 m in length and weigh roughly 1.3 kg (3 lb). They can sprint at Slow; drifts by gentle jet propulsion when hunting or escaping predators. Chambered Nautiluss are known for the living-fossil cephalopod in a spiral shell — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.
