In bilateral symmetry (also called plane symmetry), only one plane, called the sagittal plane, will divide an organism into roughly mirror image halves (with respect to external appearance only, see situs solitus). Thus there is approximate reflection symmetry. Often the two halves can meaningfully be referred to as the right and left halves, e.g. in the case of an animal with a main direction of motion in the plane of symmetry.

What are the 4 parts to a bilateral animal?
The main parts of a bilateral animal are the head, thorax, abdomen, and appendages. These structures define the basic body plan of bilateral animals and serve various functions such as feeding, movement, and sensory perception.
What is the identical or almost identical repeating body parts?
Segmented animals, such as earthworms and centipedes, have identical or almost identical repeating body parts called segments. In plants, leaves and flower petals can also be considered identical or almost identical repeating body parts.
What is the body symmetry of mussel?
Many think that the limpet has radial symmetry but this is not the case. Limpets have bilateral symmetry. Bilateral symmetry means the animal has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side. See the related link below for more information.
Type of symmetry in which body parts are mirror images of each other?
Bilateral symmetry is the type of symmetry in which an organism can be divided into two equal halves that are mirror images of each other along a central axis. This symmetry is commonly found in animals that are adapted for forward movement and have distinct front and back ends.
Do dogs have bilateral symmetry?
Yes. All birds, like all other vertebrates, have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Is a ant a bilateral?
All ants are- so are we. Bilateral symmetry means body parts are in pairs- like our arms & legs.
Do echinoderms have bilateral symmetry?
No, echinoderms do not have bilateral symmetry. They have radial symmetry, which means their body parts are arranged around a central axis.
A type of symmetry in which body parts are mirror images of each other?
Bilateral Symmetry
What type of symmetry does an animal have when the body parts are arranged in a similar ways on both sides?
"bilateral"
What are the 4 parts to a bilateral animal?
The main parts of a bilateral animal are the head, thorax, abdomen, and appendages. These structures define the basic body plan of bilateral animals and serve various functions such as feeding, movement, and sensory perception.
Is an alligator bilateral?
Yes, alligators are considered bilateral organisms because they exhibit bilateral symmetry, meaning their bodies can be divided into two equal halves along a single plane. This symmetry allows for balanced development of body parts on either side of the plane.
Is a fire ant bilateral?
All ants are- so are we. Bilateral symmetry means body parts are in pairs- like our arms & legs.
Body plan of a hookworm?
hookworms have bilateral symmetry
What did bilateral symmetry lead to the evolution of?
It allows different parts of the body to become specialized in different ways. This is called cephalization.
Is a frog a bilateral?
Yes, a frog is bilateral on the external parts. On the inside, however, they are not symmetrical.
What is the identical or almost identical repeating body parts?
Segmented animals, such as earthworms and centipedes, have identical or almost identical repeating body parts called segments. In plants, leaves and flower petals can also be considered identical or almost identical repeating body parts.
What does bilateral presence mean?
Both sides of body should shows same pulse rate, rhythm and volume. Used to check circulation in body parts after surgery
