It is called a conch. It is a home for a sea snail. A sea snail is much like that land snail you see racing across a table top, except, well, you know it’s usually in the sea. Even if you do not see it darting back and forth across your kitchen counter, you’ll know it has been there by the ectogoo it leaves behind, not unlike the contrails from passenger airliners which are used to spew hallucinogens over an (until now) unsuspecting public. If you can ever catch one of these sea snails pulling its conch/trailer down the interstate highway or camping on the ocean floor, you’ll be surprised that they are a tasty treat plus you get to keep whatever is in the trailer.
Occasionally, snails retire and move out of their conches. Their homes are then snapped up by humans who use them for musical instruments, protective gear for ancient warriors, home décor and in some cases, money, though for only a short time after it was discovered they fit poorly in the coin slots of public payphones. In theological circles, a popular topic of discussion is how many shells were picked up by Hebrews as they crossed the Red Sea fleeing Pharaoh. Some think millions of shells were transported to the Arabian desert this way while others believed all shells, fish and turtles were held back behind the walls of water parted by The Lord and whatever shells found in the desert were a result of The Great Flood. The argument rages on.
