The majority of our knowledge regarding Nautilus reproduction comes from captive species in aquaria. From these specimens, it appears that Nautilus do not have an elaborate courtship process. Males have been observed to attempt to mate with any object the same size and shape as another Nautilus. If a male is successful in finding a female, however, the mating process follows, and afterwards, the male may continue to hold onto the female for a period ranging from minutes to hours.
