POW #3

You've just discovered a rare and ancient fossil of the nautilus! The local museum of natural history is willing to pay you well for this find, but not until you reconstruct the missing fragments. Below (left) is a representation of what you have to work with.

Nautilus : mollusk with a spirally coiled shell consisting of a series of chambers; as the nautilus grows, it builds larger chambers, sealing off the old ones. A CEPHALOPOD, the animal lives in the largest and newest chamber, breathing by means of gills and feeding on crabs and other animals it catches with long, slender tentacles. Nautiluses are found in deep waters of the S Pacific and Indian oceans.
