Cephalization is the concentration of nerve cells at one end of the body. All of an earthworms sensory organs, including the nerve cells are in one part of the body. This can be proven through dissection.
earthworms travel faster
The bacteria in earthworms is called Eisenia Fetida it's in most earthworms
earthworms penises are longer
Potting mix does not kill earthworms.
Earthworms are examples of annelid worms (Phylum Annelida), which also contains leeches and many typres of marine worms. Earthworms are from the Class Oligochaeta, which contanins the earthworms, some freshwater worms and leeches.
Cephalization
A hydra does not have cephalization.
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
Cephalization means formation of a head. Cnidarians have no head, so no.
Animals with cephalization respond more quickly and in more complex ways.
Yes. They have extensive cephalization. They have a brain and eyes.
they do not
nervis system
A sponge.
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.
No, Clams are bivalvic.
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.
