A pictorial introduction to the animals that lay eggs, including chickens as well as other birds, reptiles, amphibians, fishes, insects, and even a few mammals.
Brief text and lavish illustrations explain plant reproduction and the purpose of a flower and present some plants which don't seem to be flowers but are.
Text and illustrations introduce animals with fur or hair who nurse their young, breathe fresh air, and except for two species give birth to their young alive instead of laying eggs.
