Is a bird classified as an animal?
There are many different animal classes and every animal in the world belongs to one of them. The five most well known classes of vertebrates (animals with backbones) are mammals, birds, fish, reptiles, amphibians. They are all part of the phylum chordata — I remember “chordata” by thinking of spinal chord.
Why bats are not considered as birds?
