Radial symmetry is found in the cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars).

What are the radial animals?
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.
What is an example of radial?
Examples of Radial Symmetry
Flower petals tend to extend from a central axis into a radial pattern. Fruits frequently have radial symmetry. ... Sea stars have what is called a pentamerous radial symmetry, meaning it is divided in five ways around its central point.
What animals have radial cleavage?
Radial cleavage is characteristic of the deuterostomes, which include some vertebrates and echinoderms, in which the spindle axes are parallel or at right angles to the polar axis of the oocyte.
Do fishes have radial symmetry?
Radial symmetry allows animals, such as star fish, jellyfish, corals, and sea anemones, to reach out in all directions from one central point. Animals with radial symmetry have several characteristics in common. For example, all of them live in water.
Is a jellyfish radial or bilateral?
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.
Is Sunflower a radial symmetry?
The interesting thing about a sunflower is that it contains both radial and bilateral symmetry. What appear to be "petals" in the outer ring are actually small flowers, or ray florets, which are bilaterally symmetrical. The dark inner ring, on the other hand, is a cluster of radially symmetrical disk florets.
Is Octopus radially symmetrical?
Octopuses have bilateral symmetry in their body, meaning the left side is a mirror image of the right side. ... That's because octopus arms are also radially symmetrical around the body — the arms are all around it.
What animals have 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 humans radial?
For example, take the face of a human being which has a plane of symmetry down its centre, or a pine cone with a clear symmetrical spiral pattern. ... These are radial (cylindrical), bilateral, biradial and spherical symmetry.
Is Hydra radially symmetrical?
An animal which belongs to radial symmetry doesn't really possess any left side and right side. This type of symmetry is mostly seen in phylums like ctenophora and cnidaria. As we say so we know that hydra is a cnidaria and so performs radial symmetry.
Are humans Eumetazoa?
Humans have body plans that are bilaterally symmetrical and are characterized by the development of three germ layers, making them triploblasts. Humans have true coeloms and are thus eucoelomates. As deuterostomes, humans are characterized by radial and indeterminate cleavage.
What animal phyla have bilateral symmetry?
The vast majority of animals display bilateral symmetry; also known as plane symmetry, this is a trait that applies to 99% of all animals, in the majority of phyla: Chordata, Annelida, Arthropoda, Platyzoa, Nematoda, and most Mollusca.
Is a starfish radial or bilateral?
Animals in the phylum Echinodermata (such as sea stars, sand dollars, and sea urchins) display radial symmetry as adults, but their larval stages exhibit bilateral symmetry. This is termed secondary radial symmetry.
Are sponges radial or bilateral?
Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules. Coelenterates (phylum Cnidaria) are radially symmetrical, with two tissue layers (ectoderm and endoderm) surrounding an all-purpose gastrovascular cavity.
Are worms radial or bilateral?
Worms are the first significant group of animals with bilateral symmetry, meaning that the right side of their bodies is a mirror of the left. One type of worm is the flatworm. Worms in the phylum Platyhelminthes are called flatworms because they have flattened bodies.
