Why We Need Bees, Beetles, Urchins and Worms - a quiz deck on beneficial invertebrates. Most of us think about the smallest denizens of the planet--the invertebrates--only when our houses are invaded by ants, or a bee buzzes by, or we discover a crab in a tide pool. But these organisms play integral roles in the biosphere we call home. Do you know which crustacean protects our salt marshes? Which beetle cattle ranchers rely on? Could a common mollusk help your dentist one day? Noted zoologist and author Frank Indiviglio knows a lot about the world's smallest inhabitants and brings his expertise to bear in the 48 cards of this jam-packed quiz deck, letting us know just how and why all of our diminutive neighbors are so important.
