Well it was only a matter of time before Myriam added the tunicates. Let me say that it has become crystal clear to me today what is occurring. This whole battle pits the protostomes vs. deuterstomes. The protostomes must rise up and defeat the evil empire and unjustness that is deuterstomes.

To refresh your memory or bring you up to speed, the deuterstomes are basically a superphylum that possesses the echinderms, urochordata, chordata, and hemichordata. What do these groups share in common? First, they are extremely uncool and to cheer for them makes you uncool. Second, during the development of organism when they're nothing but a clump of cells (actually a hollow sphere of cells, the blastula), the first opening (blastopore) to develop in the hollow sphere is the anus. Ewwwh, ass first! Typical of a deuterstome. Third, the cells also dived radially (cleave) and are indeterminate (the cells don't know what the want to be when they grow up).

In the cooler group, protostomes (basically every other invertebrate phyla including the molluscs). The mouth forms first, cleavage is spiral, and cells are determinate. In others words, they got they're shit together. So, so much better.

To be clear...deuterstomes=Axis of Evil. They are evil doers who threaten our very freedom. To vote protostome is to vote for justice, democracy, and freedom.
