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
"chordota" by thinking of spinal chord.
There are also a lot of animals without
backbones. These are called Invertebrates and are part of the
phylum arthropoda (arthropods). Two of
the most commonly known classes in this phylum are arachnids (spiders) and
insects.

In my next post, we will look further into each group
of Vertebrates
and Invertebrates.
There are some fascinating cut-off dates in this article however I don’t know if I see all of them center to heart. There's some validity but I will take hold opinion till I look into it further. Good article , thanks and we would like extra! Added to FeedBurner as well gsn casino games
