Vertebrates is animas that have backbone. it is mammals, birds, fish, reptiles, amphibians.

What is Mammals ? 

Ans : A mammal is an animal that breathes air , has a backbone, and grows hair at some point during its life .

In addition , all female mammals have glands that can produce milk. Mammals are among the most intelligent of all living creatures. Mammals include a wide variety of animals, from cats to humans to whales.

Mammals are warm - blooded. Mammals have backbone.

What is Birds ?

Ans : Birds are vertebrates (animals with backbones) with wings and feathers. Most birds can fly, using powerful muscles to flap their wings. But a few bird species do not have strong enough wings to fly, and so these birds are flightless.

Birds are Warm - Blooded. Birds have backbone 

What is Fish ? 

Ans : Fish have developed special senses, too. Because water transmits sounds, disperses chemicals, and conducts electricity better than air, fish rely less on their vision and more on their hearing, taste, and smell. Many can detect motion in the water using a special row of scales with sensors known as the lateral line. Others can find their prey and even navigate by detecting electrical charges.
