A native of the tropical Pacific, this cousin of the octopus has changed little in more than 150 million years. 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 parrotlike beak rips the food apart, and a radula (found in most molluscs) further shreds the food.
