The characteristics of Goldie the goldfish provide a sturdy springboard for descriptions of many other fish that react differently to everything in their environment. Goldie lives in an aquarium but her vast family lives in ponds, lakes, creeks, and oceans. We learn how they all differ in shape, movement, structure, how they breathe, see and hear, how they pro-create and protect themselves. We even get to know fish that walk, fly, and sting. A prolific author in the field of factual animal books, Fenton-through text and illustrations- succeeds in presenting a most interesting fishy world.
