CHAPTER NEW CHAPTER Vertebrate Animals the BIG idea Vertebrate animals live in most of Earth’s environments. 5.1 Vertebrates are animals with endoskeletons. 5.2 Amphibians and reptiles are adapted for life on land. 5.3 Birds meet their needs on land, in water, and in the air. 5.4 Mammals live in many environments. CHAPTER OUTLINE CHAPTER RESOURCES 5.1 CHAPTER HOME KEY CONCEPT Vertebrates are animals with endoskeletons. All vertebrate animals have an endoskeleton which includes vertebrae, or backbones. VOCABULARY Most vertebrates are fish. Fish are adapted for life in a water environment. endoskeleton vertebrate scale vertebrae CHAPTER RESOURCES SECTION OUTLINE 5.1 KEY CONCEPT CHAPTER HOME Vertebrates are animals with endoskeletons. All vertebrate animals have an endoskeleton which includes vertebrae, or backbones. VOCABULARY Most vertebrates are fish.

CHAPTER RESOURCES SECTION OUTLINE 5.2 KEY CONCEPT CHAPTER HOME Amphibians and reptiles are adapted for life on land. Amphibians and reptiles have adaptations for moving, getting food, and breathing on land. Most amphibians live in moist places. VOCABULARY ectotherm amphibian reptile CHAPTER RESOURCES SECTION OUTLINE 5.2 KEY CONCEPT CHAPTER HOME Amphibians and reptiles are adapted for life on land. Amphibians and reptiles have adaptations for moving, getting food, and breathing on land. Most amphibians live in moist places. Many reptiles live in hot, dry places. VOCABULARY ectotherm amphibian reptile CHAPTER RESOURCES SECTION OUTLINE 5.3 CHAPTER HOME KEY CONCEPT Birds meet their needs on land, in water, and in the air. VOCABULARY Birds have adaptations that allow them to survive in many environments. Many of the features and behaviors of birds relate to flight. Catching Food endotherm incubation Escaping Predators CHAPTER RESOURCES SECTION OUTLINE 5.4 CHAPTER HOME KEY CONCEPT Mammals live in many environments. Mammal species live in many environments. Mammals have adaptations that allow them to survive in cold places. They also have distinctive reproductive adaptations. VOCABULARY mammal placenta gestation CHAPTER RESOURCES Elephant Mouse SECTION OUTLINE 5.1 KEY CONCEPT CHAPTER HOME Vertebrates are animals with endoskeletons. I.
