What is the advantage of having a head with a concentration of sensory organ?
The sensory organs developed around the mouth in an attempt to help the creature eat - that being the primary reason for senses. Because all the sensory organs were concentrated around the mouth that was the beginnings of the head. So you see - the concentration of sensory organs was the reason for the head. There was no head to begin with. The head (and brain) developed because that was where all the sensory organs (and mouth) were. As for an advantage. It might be advantageous to have your sensory organs as high as possible. The reason for this is obvious for sight and sound. Smelling however would benefit more if it were located in the feet. Consider dogs and pigs. As soon as they start smelling they put their nose (and the rest of the head as well) to the ground. Feeling is not found concentrated in the head but is omni-localized.
What sense organs are located on the head and the mouth of a fetal pig?
The sensory organs located on the mouth and head of a fetal pig are not the same as adults. These organs include the eyes and nose.
In class insecta why their sensory structure is located in posterior of their abdomen?
In an insect, the sensory structure is located in the head, not the abdomen. Its sensory organs are its antennae, which allows it to smell and taste. In some insects, like cicadas, the sensory organs are in the abdomen because they lack the same antennae as other insects.
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 sense organs are located in the head and mouth of a pig?
The sense organs that are located in the head and mouth of a pig are the eyes, ears, nose and tongue. These organs are for sight, hearing, smelling and tasting, respectively.

What is the localization of a brain and specialized sensory organs of an animals head?
The localization of a brain and specialized sensory organs of an animal's head is known as cephalization. This presumed evolutionary process focuses on the creation of sensory organs in the anterior end of the head.
What is the concentration of sensory receptors in a head?
I think it is the Brain....
What is the head foot region of a cephalopod?
The “Head-Foot” region contains the mouth and sensory organs as well as the foot, the foot contains organs for locomotion.

The sensory organs located on the mouth and head of a fetal pig are not the same as adults. These organs include the eyes and nose.

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.
Why does a Hammerhead shark have a strange head?
It gives the sharks killer eyesight and they have other top-notch sensory organs.
What features of dugesia distinguish its head from its tail?
On its head the Dugesia have lateral lobes and sensory organs called eyespots with make the dugesia look like it actually has eye on its head.
Do bivalves show cephalizations?
they don't because there's no "head" bearing a cluster of sensory organs and containing ganglia to support those.
How are bivalves different from mollusks?
Bivalves have to shell parts. Another difference is cephalization. Which is the process that eventually produces a head with sensory organs.
Does the cniderian have a system?
The phylum Cnidaria encompasses over nine thousand aquatic species. All of these species share common characteristics such as being invertebrates and having no major systems. For example, instead of having a complex nervous system, cnidarians have something called a nerve net which is a simple nervous system. They lack a brain and cephalisation which means the concentration of sensory organs in the head region. However, a nerve net allows the organism to have a response to its environment. In the middle of the nerve net is a nerve ring which allows the cnidarian to swim. An example of an organism with a nerve net is a Hydra.
