# Talk:Cephalization

Why is cephalization such a common characteristic of bilaterians but seems to be entirely absent in animals with radial symmetry? What is it about the evolution of cephalization that seemingly doesn't support well a radially symmetric body plan? Momin Geoffrey (talk) 21:02, 26 January 2025 (UTC)

The article explains this quite clearly. If you habitually move in the direction of one end of your body, that end becomes the front, and can't help meeting the world first, so senses and mouth are needed to identify and process it. If you're a round jellyfish and move in any direction, you don't have a front, so it doesn't happen. Chiswick Chap (talk) 21:28, 26 January 2025 (UTC)
