I want to know the answer to the following question:
What are some examples of non-bilaterian animals?
All the background I'm provided with is that "Traditional morphological and modern molecular phylogenetic analysis have both recognized a major evolutionary transition from "non-bilaterian" animals, which are those lacking a bilaterally symmetric body plan (Porifera, Ctenophora, Cnidaria and Placozoa), to "bilaterian" animals (Bilateria) whose body plans display bilateral symmetry.". Is that enough to answer the question?
Answer: yes
