Answer:
Radial symmetry is a type of symmetry found in animals where the body parts are arranged in a circular or radial pattern around a central axis. This means that any plane passing through the center of the animal's body will divide it into two equal halves. Radially symmetrical animals are typically found in aquatic environments, where they can move in any direction to capture food or avoid predators. Examples of radially symmetrical animals include jellyfish, starfish, and sea urchins.
Bilateral symmetry is a type of symmetry found in animals where the body is divided into two equal halves along a single plane. This means that there is only one way to divide the animal's body into two equal halves. Bilaterally symmetrical animals are typically found in terrestrial environments, where they move in a forward direction to capture food or avoid predators. This type of symmetry is also associated with the development of a head region, where sensory organs and a mouth are located. Examples of bilaterally symmetrical animals include insects, fish, mammals, and humans.
