The crab that condemns itself to prison N THE Great Barrier Reef, off Australia, grow colonies of corals among which lives Hapalo carcinus marsupialis, a species of tiny crab. In securing protection against her enemies, the female crab of this species, while still young, condemns herself to prison for life. She takes up her home in the fork of two coral branches, and by constant movement sets up a current which seems to influence the coral's growth in a peculiar way. The branches broaden, curve out, then curve in again and unite over the crab's head, thus forming a round cage about the size of a marble. Small holes let the sea flow in and out, bringing the tiny particles on which the crab feeds. And there-snug, safe, protected from the hazards of her undersea world, but unable ever to venture out into that world again-she lives for the rest of her life. Shutting yourself up in a stone cell is an effec- tive way of escaping the dangers that beset the path of anyone who moves around in the world. But man can't do that-and wouldn't if he could. While man wants security, he also insists on freedom. So, very wisely, man solves his problem with insurance. You may not be able to avoid having an acci dent which could prevent you from earning a living for a long time. But through insurance, you can make certain that you will have money to pay the doctor and the hospital, to buy the medicine you may need, and to pay the rent and the grocery bills until you get well and can again earn a living for your family and yourself.
