Jellyfish exhibit radial symmetry, meaning their body can be divided into similar halves around a central axis. This type of symmetry is common among cnidarians, allowing them to respond to stimuli from all directions in their aquatic environment. This symmetry is advantageous for their predatory lifestyle as it facilitates catching prey and enduring ocean currents. Unlike bilateral symmetry found in many other animals, radial symmetry enables a more flexible and adaptive movement through water.
