Introduction To Phylum Arthropoda

  • There are about 1-2 million species of animals in the world and more than 70 per cent of these are insects. These animals are assigned to 29 phyla. Of these only nine phyla are large, and their representatives are common and familiar to us. These are called the major phyla. The other phyla are small and their representatives are uncommon and of uncertain relationships.
