Jellyfish exhibit radial symmetry, which means their body parts are arranged around a central axis. This type of symmetry allows jellyfish to respond to stimuli equally from all directions, enhancing their effectiveness as predators. Unlike bilateral symmetry found in animals like humans, radial symmetry provides jellyfish with the ability to effectively capture prey using their tentacles while floating in the water. This characteristic, combined with their gelatinous structure, enables them to thrive in various aquatic environments.
