Bones are so important not just for us but for animals as well. Let’s discover five very interesting vertebrates facts for kids.

Vertebrates Facts for Kids Fact number 1: Humans Are Vertebrates

Vertebrates are animals which have a backbone. The human backbone is called the spine and it is a very important part of the human body. It helps us stand up straight, it supports our body when we run and jump, and it protects the spinal cord which is where messages travel from our brain to our body. If we didn’t have a spine we wouldn’t be a vertebrate, other animals which are vertebrates include dogs, monkeys, fish, and birds.

Vertebrates Facts for Kids Fact number 2: There Are Five Types of Vertebrates

There arearound 54,000 species of vertebrates that live on Earth and scientists group them into different types to better study them. The five types of vertebrates are:

Mammals, that is the type that humans belong to, mammals have live young instead of laying eggs and mammals include dolphins, lions, and dogs.

Fish, they have bones that help their gills open and close so they can breathe underwater and hatch their young from eggs.

Birds which have hollow bones in their skeletal system to help them fly and hatch their babies from eggs which they usually have in nests.

Amphibians, this is the group that includes frogs, are born underwater and hatch their eggs in water.

And Reptiles, they are born with lungs on land and they include snakes and turtles.
