Hence, the earthworm exhibits cephalization.
What invertebrate group was the first to show cephalization?
platehelminthes (flat worms)
Do frog's use cephalization?
Yes, frogs exhibit bilateral symmetry. Cephalization is the concentration of nervous tissue at one end of an organism. The frog has this nervous tissue (the brain) at the anterior end of the body (the head.)
What process does the term cephalization describe?

Do bivalves show cephalization of a clam?
No - class Bivalvia of phylum mollusca have no head examples are clams, oysters, and mussels
Which phyla do not have cephalization?
Porifera (sponges), Ctenophora (comb jellies), and Placozoa do not exhibit cephalization, which is the development of a head region with sensory organs. These organisms typically lack centralized nervous systems and instead have dispersed nerve cells throughout their bodies.
List the phyla that show cephalization?
The phyla that show cephalization include Chordata (which includes vertebrates), Arthropoda (including insects, crustaceans, and spiders), Annelida (segmented worms), and Mollusca (which includes snails, clams, and octopuses).
A concentration of sense organs and nerve cells in anterior end of the body known as?
Cephalization
Does a hydra have cephalization?
A hydra does not have cephalization.
Are Cnidarians in cephalization?
Cephalization means formation of a head. Cnidarians have no head, so no.
How do animals with cephalization respond differently to the environment than animals without cephalization?
Animals with cephalization respond more quickly and in more complex ways.
What phylum is a clam?
There in the phylum Mollusca
What is the most active mollusca?

What is a snails phylum?

Do all mollusks have cephalization?
