What animals are vertabrates?

Vertebrates are animals that have a backbone, or spinal column. They are classified into five classes:

1. Mammals: These are warm-blooded animals that have fur or hair, give birth to live young, and nurse their offspring with milk. Examples include:

* Humans

* Dogs

* Cats

* Whales

* Bats

2. Birds: These are warm-blooded animals that have feathers, wings, and lay eggs. Examples include:

* Chickens

* Eagles

* Penguins

* Robins

* Ostriches

3. Reptiles: These are cold-blooded animals that have scales, lay eggs, and breathe air with lungs. Examples include:

* Lizards

* Snakes

* Turtles

* Crocodiles

* Alligators

4. Amphibians: These are cold-blooded animals that live both on land and in water. They have smooth, moist skin and lay eggs. Examples include:

* Frogs

* Toads

* Salamanders

* Newts

5. Fish: These are cold-blooded animals that live in water and breathe through gills. They have fins and scales. Examples include:

* Salmon

* Tuna

* Sharks

* Goldfish

* Eels

All animals in these five classes are considered vertebrates due to the presence of a backbone.
