| Nautilus belauensis Saunders, 1981 |
The Palau Nautilus (Nautilus belauensis) is a species of nautilus native to the waters around the Pacific island nation of Palau. N. belauensis is very similar to Nautilus pompilius and shares with this species a closed umbilicus covered with a callus. It differs on the basis of a modified radula and fine raised ridges across and along the shell, which form a cross-grid texture. N. belauensis is the second largest nautilus after the giant form of N. pompilius pompilius. The shell is usually up to around 21 cm in diameter, although larger specimens have been recorded.
