Crack, crack…animal babies are hatched all over the place. Can you figure out who’s who? Watercolor and collage illustrations depict close-up scenes of an egg or eggs about to hatch. The text hints at what the eggs contain: “Hidden in a rock cave/ Deep beneath the ocean waves/ Their mother wraps her long arms around/ To keep these eggs safe and sound.” The observant young nature lover will find a visual clue of what animal the mother might be. The next spread provides the answer-in this case, it’s an octopus. The second spread also provides fascinating facts about the species. The book features a number of species ranging from spiders to penguins to octopuses, and the back matter provides more information about the actual size of various eggs and how they develop.
