I want to know the answer to the following question:
Bilaterians are animals that have what?
All the background I'm provided with is that "Except for a few primitive organisms such as sponges (which have no nervous system) and cnidarians (which have a nervous system consisting of a diffuse nerve net), all living multicellular animals are bilaterians, meaning animals with a bilaterally symmetric body shape (that is, left and right sides that are approximate mirror images of each other).". Is that enough to answer the question?
Answer: yes
