Fascinating introduction to the world of single-celled organisms recounts the feeding, reproductive, and defensive strategies employed by an array of curious creatures: amoeba, paramecium, suctorian, hydra, others. Easy-to-understand language, 37 illustrations. Within every drop of pond water lurks an invisible world, alive with an amazing variety of microscopic animals. And with the help of this book and a microscope, you can bring these tiny creatures into focus and discover the ways in which they live. You'll trace the path of a blob-like amoeba as it stretches out its pseudopods to hunt and gobble up its prey, and you'll see the life-or-death water ballet of a slipper-shaped paramecium as it swims away from its mortal enemy, the pincushion-shaped suctorian. You'll also meet the euglena, classified as both plant and animal; the rotifer, a creature with two wheels of whirling hairlike projections that help it move by squeezing in and out like an accordion; and the incredible hydra, a fearsome bully that constantly threatens other small animals with its crown of grasping tentacles. With this book, your key to the world of single-celled organisms, you'll learn fascinating lessons about how these strange animals eat, reproduce, and defend themselves. Enter their microscopic domain and see for yourself! AGES: 8 to 14
