The Chambered Nautilus is found in underwater in the ocean. Its shadow is medium and it moves in a straight line.
The Chambered Nautilus can be donated to the museum. Upon doing so, the following text is given by Blathers:
"These creatures are related to both octopuses and squids and originated about 60 million years ago. They have air and body fluid in their shells and move by adjusting the amount of body fluid inside. This allows them to either float or sink depending on the situation they find themselves in. They have nearly 90 tentacles that can stick out from under their shells to grab on to rocks or prey.
Upon catching the fish, the player will say the following:
"I got a chambered nautilus! Who loses? Not us! Just go with it..."
