There are many differences but the major and speciifc difference is the present of diploblastic or triploblastic stage during embryonic development. Hence, in diploblastic animals there are two membranes, outer exoderm and inner endoderm, where as in the triploblastic animals there are three distinct membranes, outer exoderm, middle mesoderm and innermost endoderm. Various organs then originate from these membranes, say for example nervous system originates from exoderm primarily whereas connective tissues such as blood, muslces etc arise from the mesoderm.

In diploplastic animals the space between the exoderm and endoderm may occupied by other components say mesoglea. But there is no third distinct membrane.

In triploblastic animals, later higher in the order we will find the development of coelome.
