vertebrate an animal with a backbone
invertebrate an animal that does not have a backbone
structure is an arrangement of parts, or organs in an animal that creates something useful for the animal (such as tentacles, eyespots, gills, a stinger, wings, lungs, etc)
adapt to adjust to different conditions in the environment
environment the air, water, minerals, organisms, and all other things that surround and effect an organism at any time
exoskeleton a skeleton that is outside the animal's body. It gives protection to the animals organs and support to the animals body
endoskeleton a system of connecting bones that is inside an animal's body
warm-blooded a animal has a relatively warm body temperature that stays about the same regardless of changes in the temperature of its surroundings. Birds and mammals are warm blooded
mammals warm blooded vertebrates that have body hair, feed their young with milk from the mammary glands, and give birth to live young
mammary glands the glands in a mammal that produce milk for the young
birds warm-blooded vertebrates that lay eggs, have a body covered with feathers, and have lighweight bones, scaly leggs, wings, a beak, aqnd no teeth
cold-blooded the body temperature of the animal changes as the temperature of the surroundings change
reptiles cold-blooded vertebrates that usually lay eggs, such as snakes, lizards, crocodiles, turtles or dinosaurs. they have a covering of scales or plates and breathe through the lungs
amphibians cold-blooded, smooth skinned vertebrates which can live both on land and in the water. An amphibian hatches as a tadpole in water and breathes through gills. An adult amphibian has legs, air breathing lungs and lives on land
