Detailed explanation-3: -Sponges are an example of an animal with an asymmetric body.

Detailed explanation-4: -Asymmetrical animals are those with no pattern or symmetry, such as a sponge. Radial symmetry describes an animal with an up-and-down orientation: any plane cut along its longitudinal axis through the organism produces equal halves, but not a definite right or left side.

Detailed explanation-5: -Sponges are asymmetrical because they are extremely simple. They live in the ocean, cannot move on their own, and have no complex organs or other features that higher-order animals have. Sponges are one of only a few types of animals classified as having asymmetry.
