Organisms belonging to the phylums Coelenterata, Echinodermata and Ctenophora exhibit radial symmetry.
And here’s the answer you’re looking for. A collection of related questions and answers you may need from time to time.
Do coelenterates have radial symmetry? – Frequently asked questions
Does Coelenterata show radial symmetry?Coelenterata consists two phylum Ctenophora (comb jellies) and the Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their allies). They are radially symmetrical, diploblastic. These animals are acoelomates and they do not possess a head. Hence, the correct answer is the option D.
What kind of symmetry does Coelenterata have?So, the correct answer is option Coelenterata and Echinodermata’. Note: Many sea anemones and some corals within the Coelenterata have bilateral symmetry defined by a single structure.
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)
Is Coelenterata bilaterally symmetrical?Coelenterata is the phylum of acoelomate and radially symmetrical lower invertebrates Due to their radial body symmetry they are also known as radiata. Bilateral symmetry starts from the phylum platyhelminthes.
Is a Cnidaria radial or bilateral?Cnidarians are radially symmetric animals (e.g. sea anemones). They can be divided into two identical halves by any plane passing through the central axis of the body.
Which of the following do not show radial symmetry?Detailed Solution. The correct answer is Limulus.
What are the examples of radial symmetry?Radial symmetry relates to an arrangement around a central point, where the pattern is consistent and repeats. Common examples would be four-leaf clovers, jellyfish, sea stars, and roses. Bilateral symmetry is best described as one half of an object/organism being a mirror image of the other half.
Which organisms Cannot show radial symmetry?Generally, sponges are asymmetrical animals but few show radial symmetries. -Radial symmetry is the main characteristic features of sessile and bottom-dwelling animals such as the sea anemone and starfish. Floating animals such as jellyfish also show this symmetry.
Is Coelenterata and Cnidaria same?Coelenterata is the other name of the phylum Cnidaria. It contains mostly marine aquatic animals such as hydra, jellyfish, coral, sea anemone, etc. They are radially symmetrical and diploblastic.
What are unique characteristics Coelenterata?What are the characteristics of Coelenterates? The Coelenterates are aquatic, mostly marine organisms. The body is radially symmetrical and exhibit a tissue-level organization. Their mouth is surrounded by sensory tentacles, which helps to capture their prey.
Which of the following types of animals does not have radial symmetry?Answer and Explanation: The following types of animals do not have radial symmetry: B) arthropods, C) molluscs, and D) nematodes. Radial symmetry occurs in animals such as echinoderms, in which body parts radiate outward from a central point. This can be seen in sea stars and sea urchins.
What phylum has radial symmetry?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.
Which phylum is radially symmetrical?Complete Answer:
– The cnidarians and the echinoderms possess the radial symmetry.

- Summary: Coelenterata Coelenterates Comb jellies (Beroe spp.) Scientific classification Kingdom: Animalia Subkingdom: Eumetazoa Phylum: CoelenterataHatschek, 1888 Phyla Ctenophora Cnidaria Coelenterata is a term encompassing the animal phyla Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes from Ancient Greek κοῖλος (koîlos) ‘hollow’, and ἔντερον (énteron) ‘intestine’, referring to the hollow body cavity common to these two phyla. They have very simple tissue…

Animal Biology Notes
- Summary: Animal Biology Notes Kingdom Animalia includes all organisms that develop from a hollow ball of cells called a blastula. Most animals have well-developed motility. The simplest animals include the sponges (Porifera) and the Cnidaria. 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…

Difference Between Cnidaria and Ctenophora – Pediaa.Com
- Summary: Difference Between Cnidaria and Ctenophora | Definition, Characteristics, Similarities and Differences Cnidaria and Ctenophora are two phyla containing coelenterates with a hollow gut. Both cnidarians and ctenophores are diploblastic animals. The internal body cavity serves as the gut. The gut is covered by a tissue called gastroderm. A single opening serves as both mouth and the anus in cnidarians. However, ctenophores contain a complete…
