Description: The chambered nautilus lives in tropical waters extending from the Andaman Sea east to Fiji and from southern Japan to the Great Barrier Reef. This animal usually lives where the slopes of coral reefs descend into deep waters. During the day, it resides in dark cool waters at depths from 900 to 2,000 feet and ascends to shallower waters (300 to 500 feet deep) at night to feed.
