Animals that have backbones are called this.
vertebrates
An animal whose body temperature stays about the same is called this.
warm-blooded
Fish use these to breathe oxygen in water.
gills
The word "amphibian" means this.
"double life"
Reptiles have this type of skin that helps protect them and prevent water loss.
tough, dry, scaly skin
Animals that do NOT have backbones are called this.
invertebrates
An animal whose body temperature changes depending on its surroundings is called this.
cold-blooded
Most fish have these to help them move through the water.
fins
Young amphibians breathe with these.
gills
Reptiles breathe oxygen using these.
lungs
Scientists classify animals by grouping animals that have these similar characteristics.
characteristics/features
Cats, birds, bears, and cows belong in this temperature group.
warm-blooded
Most fish have these covering their bodies.
scales
Adult amphibians use these to breathe on land.
lungs
Most reptiles reproduce by doing this.
laying eggs
A frog, fish, snake, and cow are all examples of this type of animal because they have backbones.
vertebrates
A lizard sits in the sun because the heat from the sun does this to its body temperature.
warm it/increase its body temperature
Fish are cold-blooded animals that live in this environment.
water
The process in which a frog changes form as it grows is called this.
metamorphosis
A young reptile usually looks like a smaller version of this.
adult parent
Name two groups of cold-blooded animals.
fish, amphibians, reptiles, insects, or spiders
Name three cold-blooded animals from our lessons.
Fish, amphibians, reptiles, insects, or spiders.
Some fish lay eggs, while other fish reproduce by doing this.
giving birth to live offspring
Put these frog stages in order: adult frog, egg, tadpole, tadpole with legs.
Egg → tadpole → tadpole with legs → adult frog
According to our lesson, all animal life cycles follow this general pattern.
birth → growth → reproduction → death
