Meaningful Menagerie--The Intent

I call them Meaningful Menagerie:


Laernodiscus porcellanae--see poem previously referenced--first in series
Amblipygid
Solifugid
Tardigrade
Vestimentiferan
Loriciferan
Appendicularian
caecilian




Elaborated Echinoderms:

Cystoid
Blastoid,
Edrioasteroid,
Cyclosystoid,
Helicoplacoid
(I'm still looking for one here--a new species perhaps a new subphylum of things found in sunken logs off the coast of New Zealand some time ago.)

Xyloplax medusiformis
Concentricycloidea
