INVERTEBRATE ANIMALS - INTRODUCTION
Hello again dear readers
and sorry for being out of working.
This post is about the invertebrate animals (they are
living things, but they have not got an internal skeleton). They can be aquatic
or terrestrial and they are classified into six groups. They can be sponges,
cnidarians, worms, molluscs, echinoderms, and arthropods. Here you are some pics about the main
facts of each group.
Regards, Christopher.
