Term | Definition |
Bird | warm-blooded vertebrates with feathers.
Feathers keep the bird warm and dry |
Mammal | Warm-blooded , vertebrates with fur or hair. |
reptile | Cold-blooded vertebrates that live on land.
dry, scaly, skin.
breath through lungs. |
amphibian | Cold water vertebrates that spend some of their lives in water and part on land.
Breaths through its skin.
skin is moist
Examples are frogs, toads, and salamanders. |
cold-blooded | body temperature changes with their surroundings. |
warm-blooded | animals whose body temperature does not change much. They get heat from breaking down food. Examples are mammals, birds |
vertebrate | A back bone. A back bone allows larger and heavier animal to move about |
How are you like fish, frogs, birds, and mice? | we all have a backbone |
How is a vertebrate different for an invertebrates? | a vertebrate has a backbone and an invertebrate does not have a backbone |
Tell 2 reasons why a backbone is an important part of the vertebrate's body: | 1.supports the animal's body
2. it allows larger and heavier animal to move about |
If your bay temperature does not change much or it is a constant body temperature, what kind of animal are you? | warm blooded |
How do warm blooded animals get heat? | from breaking down food |
If you cannot keep a constant body temperature what are you? | cold blooded |
Where do cold-blooded animals get heat? | from outside their bodies |
How many classes of vertebrates are there? | 7 |
Name the 7 classes of vertebrate? | amphibians, birds, bony fish, fish, jawless fish mammals, reptiles |
Name the three classes of fish? | bony fish, cartilaginous fish, jawless fish |
What are the skeletons of jawless and cartilaginous fish made of? | cartilage |
Name two places that you have cartilage? | tip of my nose
& my outer ears |
Describe a jawless fish mouth: | boneless and like a suction cup |
Name a jawless fish: | lampreys |
Name two cartilaginous fish: | sharks and rays |
Name the largest class of vertebrate? | bony fish |
Describe the body of a bony fish: | skeleton is made of bone and it is covered with scales |
Name two bony fish? | goldfish, tuna |
Why might warm blooded vertebrates eat more often than cold blooded vertebrates? | Warm blooded vertebrates maintain a constant body temperature by getting heat from the food they break down. |
How are the 3 classes of fish alike? | live in water & they are cold-blooded |
Name 5 classes of cold-blooded vertebrates? | 3 classes of fish - bony fish, cartilaginous fish, jawless fish

What do frog eggs hatch into? | tadpoles |
How do tadpoles breathe? | gills |
When a tadpole changes what new body part allows it to live on land? | lungs |
How does an adult amphibian breathe? | through its skin |
Why must an amphibian live near water? | to keep its skin moist so it can breathe |
Name the cold blooded vertebrate that lives on land? | reptile |
Describe a reptiles skin so I know why it can live on land? | dry skin, covered in scales that is waterproof |
How do reptiles breathe? | through their lungs |
What is the only animal that has feathers? | birds |
How do feathers help a bird? | keeps it warm and dry |

life cycle | stages of growth and change |
life span | how long it can live |
metamorphosis | this process has several separate growth stages. Butterflies and other insects go through this process. |
incomplete metamorphosis | growth stages that are hard to see |
complete metamorphosis | each growth stage looks different. Egg, larva, pupa, adult |
clone | an exact copy of its parent |
