Fish And Amphibians!

Hello,

Animals that have a backbone are called vertebrates.  Do you have a fish?  I don't because I have four dogs!  There are three types there is a bony fish, a cartilage fish and a jawless fish.  Fish are cold-blooded.  Cold-blooded means it's body temperature changes with the temperature of it's environment.  Fish have scales, just like people have skin.  Some fish live in fresh water such as streams and lakes.  But some live in the ocean,too.  Your skeleton has some cartilage and many bones.  Now to the amphibians.  Like fish,amphibians they are also cold-blooded vertebrates.  Amphibians are an important part of the environment.  Fish and amphibians are so cool!  Thanks for reading!Bye,Bye
