This work is for ages 6-12. The text is in Spanish. Amphibian means 'two lives' since these animals spend the first part of their life underwater and the rest on land. From flying tree frogs to slithering caecilians, kids will be captivated by this 'slimy' animal group in this book. Readers will discover: the amphibian family tree; an amphibian's body; special skin and senses; how they move and what they eat; water-versus land-dwelling species; their life cycle and parental care; defending themselves.
