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 fish radial symmetrical?
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.
Is radial symmetry found in starfish?
Sea stars, and other echinoderms, move and feed like no other animals. ... Based on five-part radial symmetry (though some sea stars have many more arms), key functions are coordinated in the center of their bodies, then passed down the arms.
Does a sea anemone have radial symmetry?
Radial symmetry: Some organisms, like sea anemones (phylum Cnidaria), have radial symmetry.
Which animal phyla has 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.
Are jellyfish radially symmetrical?
Jellyfish and many other marine animals such as sea urchins, sea stars, and sea anemones have what is known as radial symmetry.
What type of symmetry do jellyfish have?
The body of a jellyfish exhibits radial symmetry and is divided into three main parts: the umbrella, the oral arms (around the mouth) and the stinging tentacles.
Do sea cucumbers have radial symmetry?
Sea cucumbers are echinoderms, a phylum that includes sea urchins and starfish. Echinoderms have a five-way radial symmetry, a pattern most familiar in the shape of the starfish. In sea cucumbers this character is shown in the five strips of muscle inside the body wall, running from the front to the back.
Is Octopus radially symmetrical?
Octopuses have bilateral symmetry in their body, meaning the left side is a mirror image of the right side. ... Octopuses, however, don't have to have a preferred direction. That's because octopus arms are also radially symmetrical around the body — the arms are all around it.
Is Hydra radially symmetrical?
Hydra has a tubular, radially symmetric body up to 10 mm (0.39 in) long when extended, secured by a simple adhesive foot known as the basal disc.
Are arthropods radial or bilateral?
One character inherited by all arthropods is bilateral symmetry.
What animals have no bilateral symmetry?
They start off symmetrical, but as adults they get that wandering (literally) eye that shifts to one side of their face, so that they can hide flat in the sand and see their prey above. Narwhals. Their unicorn horn is actually one of their incisor teeth that grew straight through their face. So it's off to the side.
Where are tentacles on Cnidaria?
Cnidarians, such as jellyfish, sea anemones, Hydra and coral have numerous hair-like tentacles. Cnidarians have huge numbers of cnidocytes on their tentacles. In medusoid form, the body floats on water so that the tentacles hang down in a ring around the mouth.
Does Cnidaria have radial symmetry?
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.
Do annelids have radial symmetry?
Annelids display bilateral symmetry and are worm-like in overall morphology.
Do reptiles have bilateral symmetry?
Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
