What does bilateral symmetry enable?
Bilateral symmetry allows for the animal to have directed movement, which can help when searching for food or escaping predators. Also, it allows for quicker and precise response to stimulation, since the nervous system is cephalized and much more complex than in organisms without bilateral symmetry.
How would having sense organs in front be helpful to an animal?
Having sense organs in front of an animal would provide better spatial awareness, allowing the animal to detect its surroundings more effectively and react to potential threats or opportunities quickly. This positioning can also enhance the animal's ability to navigate and interact with its environment with precision.
What is the semetry of platyhlminthes?
Platyhelminthes, commonly known as flatworms, exhibit bilateral symmetry, meaning their body can be divided into two mirrored halves along a single plane. This symmetry is associated with their streamlined body shape, which facilitates movement and predation. Additionally, many flatworms display cephalization, where sensory organs and nerve tissues are concentrated at the anterior end, enhancing their ability to respond to the environment. Overall, bilateral symmetry is a key characteristic that distinguishes them from other phyla with different symmetry types.
Body is divided vertically into equal left and right halves?
This is the concept of bilateral symmetry. It means that the body can be divided into two equal halves along a vertical plane, resulting in mirrored halves. Bilateral symmetry is common in many organisms, including humans.
What type of body cavity do mollusks have?
Annelids exhibit bilateral symmetry.
Where are nerves and sense organs of animals with bilateral symmetry located?
anterior end
What does annelids show by having bilateral symmetry with an anterior head where most sense organs are found?
Cephalization
Do animals with bilateral symmetry have a distinct head end?
Yes, animals with bilateral symmetry typically exhibit a distinct head end, known as the anterior. This feature is part of a body plan where the left and right sides are mirror images, allowing for streamlined movement and directional locomotion. The presence of a head end often includes the concentration of sensory organs and neural structures, enhancing the animal's ability to interact with its environment.

What kind of body symmetry do vertebrates have?
Symmetry in animals is something that is very important. It is a big part of classification in animals. Nearly all multi-cellular organisms exhibit one or other type of symmetry such as radial or bilateral. For more on this see the source.
What type of symmetry do lizards have?
Lizards typically exhibit bilateral symmetry, which means their bodies can be divided into two equal halves along a single plane. This symmetry allows for balanced movement and coordination in their limbs and organs. While some lizards may also display radial symmetry in certain body parts, such as their eyes or scales, bilateral symmetry is the most common form found in these reptiles.
What is an advantage of bilateral symmetry?
Celiaphlatus and forward movement. There is a few advantages of the bilateral symmetry. Some of the advantages are food, movement and animals.
What are the worms characteristics?
They have bilateral symmetry, many have appendages, some have sense organs, some have light sense organs have smooth bodies, able to rejoin bodies and are invertebrateslong and slimy

What symmetry does a mouse have?
A mouse exhibits bilateral symmetry, meaning its body can be divided into two mirror-image halves along a single plane that runs from its head to its tail. This type of symmetry is characteristic of many animals, allowing for streamlined movement and a more organized body structure. Additionally, bilateral symmetry often correlates with the development of a centralized nervous system and paired sensory organs.
What are disadvantages of bilateral symmetry?
With bilateral symmetry the sensory organs tend to group toward the anterior (front) normally around the head. This means that while you may have more brainpower you may not have the ability to see things behind you or to have the ability to smell by touch. These may not be the coolest abilities but they are interesting and animals with bilateral symmetry don't tend to have them. The sensory organs are not evenly distributed. Also, animals with radial symmetry can reach out on all sides and therefore have a better chance against predators in that sense.
What kind of symmetry does a human have?
None. Even the most symmetrical face is not totally symmetrical. And since the heart, stomach, liver etc are on one side of the body, the internal organs are certainly not symmetrical.
