How do upsidedownjellyfish protect itself?

Upside-down jellyfish, primarily found in shallow coastal waters, protect themselves through a combination of stinging cells called nematocysts, which can deter predators, and their unique behavior of lying upside down on the seafloor. By doing so, they can also engage in symbiOSis with photosynthetic algae, which provides them with nutrients and enhances their survival. Additionally, their gelatinous bodies and low mobility make them less appealing to many larger predators.
