Jellyfish bodies are supported by the water they live in. Furthermore, if jellyfish had a strong skeleton, then they would need more energy to swim.
Jellyfish do not have wings they have tentacles to help them swim under water!EXTRA INFORMATION:if you have ever seen a jellyfish swim, you would have noticed that all of their tentacles move swiftly at the very same time.
