    Name the two subkingdoms of animals mentioned in the text and briefly describe the key differences between them.

    <p>The two subkingdoms of animals mentioned are Parazoa and Eumetazoa. Parazoa animals lack tissues organised into organs and have indeterminate shape, and are asymmetrical. Eumetazoa animals have tissues organised into organs and organ systems and can be either radially symmetrical or bilaterally symmetrical.</p> Signup and view all the answers
