How would I identify by:
tissue presence, symmetry, germ layers, digestive system development, body cavity type
For each phyla:
the common name, a representative member, and
a description, including at least two characteristics unique to that phylum (and that distinguish it from other closely related phyla)
Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Nematoda, Arthropoda, Echinodermata, and Chordata
Thank you soooo much to whoever can help with this!
