Do annelids have radial symmetry?

Annelids display bilateral symmetry and are worm-like in overall morphology.

What symmetry do annelids have?

The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species.

Which does not show radial symmetry?

Detailed Solution

The correct answer is Physalia. Physalia is bilaterally symmetrical.

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.

Which group has radial symmetrical?

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 arthropods radial or bilateral?

One character inherited by all arthropods is bilateral symmetry.

Which of the following animal phyla exhibit radial body symmetry?

Animals in the phyla Cnidaria and Echinodermata generally show radial symmetry, although many sea anemones and some corals within the Cnidaria have bilateral symmetry defined by a single structure, the siphonoglyph.

Are chordates bilateral symmetry?

Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation. ... The Chordata and Ambulacraria together form the superphylum Deuterostomia.

What is an example of radial symmetry?

Examples of Radial Symmetry

Think of an orange or apple that has been cut into wedges. The seeds within the fruit are distributed in a radial pattern. In the animal kingdom, there are two broad phyla that exhibit radial symmetry: One of these is cnidarians, which include jellyfish, anemones, and corals.

Does nereis have radial symmetry?

Coelenterata (Cnidaria) and Echinodermata phyla have a radial symmetry in its body organization whereas Nereis has a bilateral symmetry in its body organization. Coelenterata are aquatic, mostly marine, sessile or free-swimming, radially symmetrical animals.

Do echinoderms have radial symmetry?

Adult echinoderms have radial symmetry. This is easy to see in the sea star and sand dollar in Figure above. However, echinoderms evolved from an ancestor with bilateral symmetry. Evidence for this is the bilateral symmetry of their larvae.

Are Cnidaria radial or bilateral?

Based on both the polyp and medusa body plans, cnidarians are classified as having radial symmetry. All cnidarians have a central point or axis, and if you divide a cnidarian through this central axis, you'll end up with equal parts on either 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.

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.

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.

What is radial symmetry and bilateral symmetry?

Definition. Radial Symmetry: The organism's body generates identical sides in any plane which it is divided along the central axis. Bilateral Symmetry: The body of the organism generates two sides as left and right along the sagittal plane. The two sides are the mirror image of the other.
