With vibrant hues and a treasure trove of fascinating facts, the creator of A Is for Australian Animals celebrates biodiversity among the sea creatures living in reefs along the shore. Along the Australian coastline, underwater reefs are bustling with the most amazing sea creatures living on the planet. What can blow bubble rings and swim through them? What has teeth on its eyeballs? What creature makes itself nearly invisible to predators by using camouflage? What poops out sand? More than 25 percent of all sea creatures live in coral reefs, also called "rain forests of the sea." This book introduces readers to everything from playful dolphins to deadly Irukandji jellyfish, leafy sea dragons to brainy octopuses, and walking sharks to whimsical-looking zebra seahorses. With gorgeous patterns and colors and substantial entries exploring each creature's anatomy, diet, threats to survival, and more, Frané Lessac brings us a truly fascinating undersea exploration of the awe-inspiring Australian reefs.
