Leafy Sea Dragons [PDF ebook] 

Off the southern and western coasts of Australia lives a fish with transparent fins shaped like seaweed, undulating slowly in the water, mimicking its plant surroundings to survive. This incredible example of evolution is an endangered species, a sad reality but a great opportunity to teach. This book highlights the incredible physical attributes of the leafy sea dragon through astonishing full-color photographs, and includes wacky tidbits on every page to entice readers of all ages into learning about biology, ecosystems, and more!
