With over two million known species, the Kingdom Animalia is the largest grouping in classification of living things. Its members are divided into approximately 30 phyla. Over 95 percent of animal species are invertebrates (without back bones). Invertebrates include a vast array of varied organisms in many different phyla, from sponges to insects. It is believed that as many as 10 million species may still await discovery. Vertebrates form part of the Phylum Chordata. Although they total only about 45000 species, they include the largest and most familiar members of the animal kingdom, and also human beings.
However the "most merciful creator" did not send any messenger for the other animals. What would be their fate in the life here-after?
