 note = {Experiments on the reproductive behavior of Nautilus belauensis brought from
Palau were carried out in the laboratory, and newly-devised tank was used for this purpose.
It was seen that on most occasions, copulation took place successfully, and eggs
were laid by the three Nautili. From the observations carried out, copulation lasted between 15 minutes to one hour at the most. Also, copulation took place mostly at night
and early morning. The time span of egg spawning was about one hour, and the egg
size ranged from 3-4cm in length. It was also noticed that most of the eggs were laid
inside of the vessels.},
