Reptiles, amphibians and fishReptiles have scales. Reptiles are born on land. Reptiles are cold-blooded which means their bodies change temperatures with the outside temperature around them. Reptiles lay eggs, and their babies hatch from those eggs. All amphibians begin their life in water with gills. As they grow, they develop lungs – which is what they use to breathe with on land. They grow legs to use on land too. Fish use gills to breathe. A fish stays in the water for its entire life! Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1
