Does a jellyfish have a symmetrical body? Like all members of the phylum, the body parts of a jellyfish radiate from a central axis. This “
radial symmetry
” allows jellyfish to detect and respond to food or danger from any direction. Jellyfish have the ability to sting with their tentacles.
Is a jellyfish asymmetrical or symmetrical?
Despite the diversity within the jellyfish clade, Medusozoa, all 200 described jellyfish species exhibit
radial symmetry
. This means that their appendages radiate outward from a central point – akin to the spokes of a bicycle wheel.
Why are jellyfish radially symmetrical?
This form of symmetry marks the body plans of many animals in the phyla Cnidaria, including jellyfish and adult sea anemones (Figureb, c). Radial symmetry
equips these sea creatures (which may be sedentary or only capable of slow movement or floating) to experience the environment equally from all directions
.
Do jellyfish exhibit bilateral symmetry?
Which organism has a symmetrical body?
Thus, only one plane of symmetry will divide a bilateral animal into symmetrical halves, the median longitudinal, or sagittal, plane. Bilateral symmetry is characteristic of the vast majority of animals, including
insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans
.
Is the body symmetrical?
The body plans of most animals, including humans, exhibit mirror symmetry, also called bilateral symmetry
. They are symmetric about a plane running from head to tail (or toe). Bilateral symmetry is so prevalent in the animal kingdom that many scientists think that it can’t be a coincidence.
What is symmetrical body shape?
A symmetrical shape is
any shape the body makes which, if divided down the middle with an imaginary line, would show that each side is the same and forms a mirror image of the other side
.
Is a squid bilateral symmetry?
Like all other cephalopods, squid have a distinct head,
bilateral symmetry
, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles.
What is radially symmetrical body?
Definition of radial symmetry
:
the condition of having similar parts regularly arranged around a central axis
.
Which of the following is an example of a symmetrical animal?
Examples of animals that possess bilateral symmetry are:
flatworms, common worms (“ribbon worms”), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates
.
Which animal has a bilaterally symmetrical body plan?
People, dogs, cats, and elephants
all have bilateral symmetry. Animals with radial symmetry have body parts arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves. Animals with radial symmetry have many lines of symmetry.
What animals are not symmetrical?
- Plaice. Plaice refers to a group of flatfish that is made up of 4species (scale-eye, Alaskan, American, and European plaice). …
- Wrybill. …
- Fiddler Crab. …
- Narwhale. …
- Sperm Whales. …

Which of the following animals has bilateral symmetry?
So, the correct answer is ‘
Earthworm
‘
What type of symmetry do jellyfish have?
Jellyfish and many other marine animals such as sea urchins, sea stars, and sea anemones have what is known as
radial symmetry
.
What is symmetrical and asymmetrical?
Symmetrical balance (or Symmetry) means that the work of art is the same on one side as the other, a mirror image of itself, onboth sides of a center line. Asymmetrical balance (or Asymmetry) means that the two halves of the work of art are different, however, try to create balance.
Are all animals symmetrical?
Importantly, she notes,
not all animals are bilaterally symmetrical
. Some animals have radial symmetry with four or five axes, like starfish, jellyfish and sea urchins. The only creature on Earth who is not symmetrical in any way is the sponge.
Are all bodies asymmetrical?
We are all born as asymmetrical beings
. ALL of our systems, the way we move, see, think, hear and breathe all require us to be asymmetrical to function.
Are both sides of body symmetrical?
What parts of the body are asymmetrical?
What are the symmetrical objects?
Symmetrical objects: An object is symmetric if we can divide the object into two identical parts. Many things in our surroundings are symmetrical objects. Some of them are
Spectacles, Lock, Glass, Ball and Pot
.
What is an asymmetrical body?
Bilateral organisms exhibit similarities between left and right sides. Radially symmetrical organisms have body plan in which every side is the same around an axis. In contrast, there are
organisms lacking external symmetry
and are described as asymmetrical.
What is asymmetrical example?
Asymmetry exists when the two halves of something don’t match or are unequal.
The American flag
is an example of asymmetry. If you understand symmetry, you’re on your way to understanding asymmetry.
Is a starfish symmetrical?
What symmetry is a snail?
For most animals, the left half of the body is pretty much a mirror image of the right half, at least on the outside. One exception to this
bilateral symmetry
is found in snails, whose shells spiral to either the right or the left.
What symmetry is a shark?
morphology. It has a
Bilateral symmetry
.
What animal has radial symmetry?
Radial symmetry is found in the
cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars)
.
Are starfish radial or bilateral?
We concluded that starfish are
slightly bilateral
in behavior, and they are, to some extent, bilateral animals.
What is an example of a radially symmetrical body?
Terms Definitions | Bilateral symmetry equal on both sides, down the middle | Radial symmetry an organism can be divided equally about a central point, much like a pie cut into equal parts | Cnidarians include jellyfish, anemones, and corals | Echinoderms sea stars, urchins, and sea cucumbers |

What symmetry do cnidarians have?
What is bilaterally symmetrical body?
What type of symmetry do cnidarians have?
The
bilateral symmetry
of Cnidaria is thought to be inherited from the common ancestors of both cnidarians and triploblastic bilaterians. The secondary radial symmetry of Cnidaria evidently is a result of the adaptation to the sessile mode of life.
Is a starfish symmetrical?
What symmetry is a starfish?
Starfish typically show
pentameral symmetry
, and they are typically similar in shape to a pentagram. Although starfish can evolve and live with other numbers of arms, the dominant species always show pentameral symmetry.
What type of symmetry does a turtle?
The scutes of a turtle’s carapace are arranged in longitudinal rows with
strict bilateral symmetry
in organization.
