About the Game

As a science journalist hosting a symposium on the chambered nautilus, you're counting on a renowned expert to close the show. When they mysteriously fail to appear, you must balance running the event with searching the aquarium. Can you find the missing expert and save the symposium before time runs out?

Endangered Rescue: Chambered Nautilus is an 18Escape adventure created in partnership with Science Friday to support Cephalopod Week. Every game purchased supports independent science journalism. Stay connected to the awe and joy of science all year with Science Friday's flagship newsletter Week in Science.
