Compare and contrast feautures across phylum:

Porifera, Cnidaria, Ctenophora, Platyhelminthes, Nemertea, Mollusca, Annelida, Blastocoelomates (Phylums Rotifera, Nematode, Entoprocta), Arthropoda (Phylums Tardigrade, Onycophora), Echinoderms, Locophore (Phylums Phoronida, Ectoprocta, Branchiopoda), Protochordates (Phylums Hemichordate, Chordata)

What are the big issues related to their convergent evolution, solutions to the problem of their body plan?

What are their forms of development?

Diagram each phylum's water flow. C

ompare and contrast features across Phylums: circulatory system, gas exchange, feeding, syncytial or not, ciliated or not (in short)

Thank yoooou!

There are nine major phyla described - Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, 1. which of these do you consider to be the most successful? 2.Explain your rationale for measuring success (e.g. total numbers, numbers of different species within the phylum, adaptability, specificity etc) and choose a representative animal within that phylum and discuss which aspects of its physiology and lifestyle have contributed to its success.

i) How does the ability of phyla Annelida to move compare with the phyla Platyhelminthes, which prominently use adhesive/releaser glands to facilitate movement? Describe their movement using two examples from specific groups of annelids (structures & how it's used) in one or two paragraphs. ii) Describe the circulatory & nervous systems of phyla Annelida and how they relate to their metamerism. Finally, iii) compare your answer from part iii with the myriapods found in the phyla Arthropoda.
