Taxonomy question

[Golfguy]

Qvault lists arthropods as being pseudocoelemates, while other sources list them as coelemates. Nematodes as being pseudo by wiki, and platyhelminthes as being acoelamates. What groups are what, I can't seem to get this straight?

Thanks!

Platyhelminthes = acoelomate
Nematoda = Pseudocoelemate
Rotifera = Pseudocoelemate
Arthropods/Mollusk/Echinoderms/Chordata = Coelomate

I agree with that! I think Arthropods have a coelem. Cnidaria and Porifera are also acoelomates.

Qvault needs to change their illustration on this.

The info posted by bharat jives with wiki and other sources. I'm just not sure how deep I need to go. As in the knowing the three near extinct tracheophytes, nervous systems, ect....
