Compare and contrast two invertebrate phyla using developmental characteristics that are used for classification in the current phylogenetic tree. Be sure to include at least two similarities in the phylum and two differences in the phyla.

The vertebrates such as the Anthropoda & Annelida are similar in their segmented bodies, brains and complete digestive systems while

Mollusks, annelids, and arthropod are protostomes and Echinoderms and chordates are deuterostomes. Anthropoda and echinodermata  have exoskeleton and endoskeleton respectively.

NOTE:

Protostomes and Deuterostomes

Most invertebrates (and higher animals) can be placed in one of two groups based on how they develop as embryos. The two groups are called protostomes and deuterostomes. The organisms in the two groups have different ways of forming the coelom and mouth.
