Miner A LEATHERY, BROWN TRAPDOOR PROTECTS THE CHAMBERED NAUTILUS FROM INTRUDERS When the coast is clear, out venture a multitude of pale tentacles, followed by two buttonlike, lensless eyes. Then appears the siphon. A stream flushes through it, and the animal, squidlike, shoots backward, shell and all. This survivor from early geologic times swims about near the floor of the ocean hunting shrimp or other bottom creatures. Sometimes it turns itself upside down and walks about, using its tentacles as feet. Native fishermen of the Philippines and the Netherlands Indies export the shell to China, where it is made into mother-of-pearl ornaments.
