*Invertebrates are the animals do not posses backbone.
*Vertebrates are the animals that posses backbone
*Pylum porifera do not contain any tissue and it is assymetry.
* Bilateria Possess bilateral symmetry and true tissues and three germ layers and most have a complete gut.
* Chordata Possess notochord
*Tetrapods consists limbs and legs
*Cnidirians are the animals that possess radial symmetry and true tissue ,two germ layers and gastrovascular cavity along with special cnidoblast stinging cells.
*Protostomes are the animals in which mouth first forms from blastopore.
*Deuterostomes are the animals in which mouth form se ond opposite to blastopore.
*Echinodermata is the phylum which contain spiny skin and calcareous endoskeleton along with vascular system.
