To answer this question, I would need to know which specific animal you are referring to. The type of body symmetry an animal exhibits is a characteristic of its species, and different animals can have different types of symmetry. There are three main types of symmetry in the animal kingdom:

1. Asymmetrical: In this type, there is no symmetry; no matter how you try to divide the animal, you cannot get two halves that are mirror images. A common example of asymmetrical animals is sponges.

2. Radial: Radial symmetry means that the animal's body parts are arranged around a central axis. Any plane passing through this central axis divides the organism into two halves that are mirror images. Examples include sea stars (starfish), jellyfish, and sea anemones.

3. Bilateral: Bilateral symmetry is where the animal can be divided down its length into similar right and left halves along only one plane. Most animals, including humans, exhibit bilateral symmetry. It is associated with cephalization (the development of a head region with sensory organs and a mouth).

Please provide the name of the specific animal or describe its features, and I can tell you what type of body symmetry it exhibits.

Extra: Symmetry is a fundamental aspect of biological organization. Asymmetry tends to be the most primitive form of organization observed primarily in sessile or slow-moving animals without a central nervous system. Radial symmetry is typical of sessile or planktonic (free-floating) organisms, allowing them to experience the environment equally from all sides. Bilateral symmetry is associated with a more active lifestyle and is common in animals that are mobile and have centralized nervous systems, which enhance directional movement and sensory perception. Understanding the symmetry of an animal can provide insights into its lifestyle, habitat, evolutionary history, and even how it interacts with its environment.
