Summary Introduction
Introduction: Animal phylogeny is the rapidly changing field for the biologists. Even if the members of animal kingdom are incredibly diverse, there are various animals sharing certain features that differentiate them from other organisms of the kingdom.

Students have asked these similar questions
Mollusca (clams, abalone, nudibranchs, snails, squid, octopi,
etc).
Unifying features include shell, mantle, radula, foot, visceral
mass
Which classes show a loss of the shell. How does the shell
benefit an organism, how does the loss of the shell benefit other
members of this phylum?
Distinguish between polyplacophora, bivalva, gastropoda, and
chephalopoda

them?

a. Mollusca
b. Brachiopoda
c. Bryozoa
d. Annelida
Which of the following combinations correctly matches a phylum to its description?
