Chordates includes a bit more than just vertebrates, it also includes tunicates, which includes sea squirts, salps and larvaceans. And the other being the cephalochordates, which today only just includes the lancelets, all others are extinct.

The phylum is not "echnoderm" it's echinoderm. Echino = spiny, derm = skin, like the sea urchin.

What about ctenophorans, bryozoans, nemerteans, cycliophorans, entoproctans, onychophorans, tardigrades, nematomorphs, loriciferans, priapulids, kinorhynchans and hemichordates?

They are considered to be "smaller" Phyla. And since he is referring to the most potent and abundant animals only the 9 prime Phyla are discussed in this little video. Although that doesn't mean the animals you mention don't deserve to be studied because they are not as common. Not at all. But they would be more appropriate to be studied in a more in depth look into the kingdom Animalia.

@@mariannaluciliasericata4195 Is there anywhere I could find a comprehensive list of every animal phylum that's ever been named? I still have a special interest in phylogeny.
