To avoid predators by day, nautilus linger along deep reef slopes as deep
as 2,000 feet. At night, they migrate to shallower waters and cruise the reefs,
trailing their tentacles in search of food.
Its simple eyes can only sense dark and light, but the nautilus uses more than 90 tentacles—the most of any cephalopod—to touch and taste the world. A nautilus’s tentacles, unlike those of other cephalopods, have grooves and ridges that grip food and pass it to the nautilus’s mouth. A parrotlike beak rips the food apart, and a radula further shreds the food.
