"Cephalization" means that the animal has a defined "head" region in which there is a lot of nervous tissue (such as the brain in humans). Sponges are not cephalized because they do not have defined head region nor do they have a central location for their nervous system. The nervous system in sponges is very loose because their cells generally work more individually as opposed to being commanded by a nervous system.

Are Cnidarians in cephalization?

What does cephalization refer to?
Cephalization refers to the gathering of neural tissue towards the anterior or posterior for means of central control. In arthropods, cephalization has formed the brain in the head of the animal, usually consisting of the first three ganglia of the paired nerve cords.
Do nematodes show cephalization?
Phylum Nematoda does exhibit cephalization. Cephalization is a evolutionary trend in development in which the sensory and neural organs of a species becomes concentrated on one end of an organism.
Is cephalization apparent in a clam?
No, Clams are bivalvic.
