What is radial symmetry and which group of animals exhibit this type of symmetry?

Radial symmetry is a condition in which the parts of the body are arranged around a central axis in such a way that any plane passing through the central axis divides the animal into halves that are almost mirror images of each other. The group of animals exhibiting this type of symmetry includes cnidarians (coelenterates) such as sea anemones. Signup and view all the answers

Briefly explain what bilateral symmetry is and provide examples of animal phyla included in the grade Bilateria.

Bilateral symmetry is when an animal's right side is approximately the same as the left side and can be divided into two equal parts by an imaginary line in one plane. Animal phyla included in the grade Bilateria are Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata, Hemichordata, and Chordata. Signup and view all the answers

Describe the characteristics of animals in the grade Bilateria.

Animals in the grade Bilateria have a distinct anterior and posterior end, clearly defined dorsal and ventral surfaces, and are triploblastic. They may be acoelomate, pseudocoelomate, or coelomate. Signup and view all the answers

Explain the development of bilateral symmetry in Echinoderms and its significance.

Echinoderms have developed bilateral symmetry in their larvae, but as adults, they have secondarily developed radial symmetry due to their special mode of life. Signup and view all the answers

What is the significance of the inclusion of animals with bilateral symmetry in the grade Bilateria?

The inclusion of animals with bilateral symmetry in the grade Bilateria highlights their shared characteristic of having distinct anterior and posterior ends, clearly defined dorsal and ventral surfaces, and being triploblastic. Signup and view all the answers
