Earthworms have
bilateral symmetry
. This means that if you cut the earthworm down the centerline, the left side of the body would be identical to the right side.
Does earthworms have bilateral symmetry?
Earthworms
have bilateral symmetry
. This means that if you cut the earthworm down the centerline, the left side of the body would be identical to the right side. Some species of earthworms have a tongue-like lobe above the mouth called prostomium
Do earthworms have radial or bilateral symmetry?

it has radial symmetry
. What kind of symmetry does an earthworm have? Bilateral symmetry if you cut it down the middle.
Do earthworms show radial symmetry?
Yes, it has radial symmetry
. What kind of symmetry does an earthworm have? Bilateral symmetry if you cut it down the middle.
Do amphibians have radial or bilateral symmetry?
Amphibians have
bilateral symmetry
. This kind of symmetry means that their body can be divided into a right half and left half. This type of symmetry…
Is a human radial or bilateral?
Chordates like humans have
bilateral symmetry
, which means you can divide them into a left and right half, and that they have a defined top, bottom, front and back.
What is radial symmetry give an example?
Radial symmetry is a form of symmetry in which identical parts are arranged in circular fashion around the central axis. Thus, cutting it through the central axis in any direction gives identical parts. Eg-
Hydra, Obelia (Coelenterata)
, starfish etc.
What animals show radial symmetry?
Animals with radial symmetry have many lines of symmetry. Because of the circular arrangement of their parts, radially symmetrical animals do not have distinct front or back ends. They may have distinct top and bottom sides. Some examples of these animals are
jellyfish, sea urchins, corals, and sea anemones
.
Which animal has a bilaterally symmetrical body?
Examples of animals that possess bilateral symmetry are:
flatworms
Do jellyfish show bilateral symmetry?
Jellyfish are not the only example of
radially symmetric organisms
in the world. In fact, most members of the phylum to which jellyfish belong, Cnidaria, exhibit radial symmetry, including most hydras, corals and sea anemones. … Nevertheless, radial symmetry is not restricted to the animal kingdom.
What are the 3 types of symmetry?
Animals can be classified by three types of body plan symmetry:
radial symmetry, bilateral symmetry, and asymmetry
.
What is radial and bilateral symmetry?
radial symmetry: a
form of symmetry wherein identical parts are arranged in a circular fashion around
a central axis. bilateral symmetry: having equal arrangement of parts (symmetry) about a vertical plane running from head to tail.
Does a jellyfish have radial symmetry?
Jellyfish and many other marine animals such as sea urchins, sea stars, and sea anemones have what is known as
radial symmetry
.
Are starfish radial or bilateral?
We concluded that starfish are
slightly bilateral
in behavior, and they are, to some extent, bilateral animals.
What is the advantage of bilateral symmetry?
The advantages of bilateral symmetry include
the formation of a head and tail region
, where the head region can house a detailed nervous system, and more directional movement to include the ability to move straight forward.
How do the general lifestyles of radial and bilateral animals differ?
All radially symmetrical animals are
aquatic and their body has an oral and another aboral side
. Compared to this a bilaterally symmetrical organism has anterior/posterior, left/right and dorsal/ventral sides. Bilaterally symmetrical organisms develop head-like structure or proper head, i.e. there is cephalisation.
