The Egg - Tapa dura

Reseña del editor

This book reveals the mystery of the egg. The inside story is told from the first glimmerings of life growing inside the shell to the animals' struggle to be free. Over 200 action photographs capture each stage of the hatching process, from a penguin to a cygnet, from a gecko to a trout. The text guides the reader through the way that fishes, birds, reptiles, molluscs, amphibians and insects ensure the success of their eggs. Every aspect of the egg is explored. How many eggs can a domestic duck lay in one year? Do chicks communicate from inside the egg? How can a swallowtail caterpillar be larger that the egg it emerges from?
