. . . you may think of a rock pool as an entity; though, of course, it is not. The waters of its consciousness--so to speak--are swarming with hunted anxieties, grim-jawed greeds, dartingly vivid intuitions, old crusty-shelled rock-gripping obstinacies, deep-down sparkling undiscovered secrets, ominous protean organisms motioning mysteriously, perhaps warningly, toward the surface light. How can such a variety of creatures coexist at all? Because they have to. The rocks of the pool hold their world together. And, throughout the day of the ebb tide, they know no other.
