Can you touch a jellyfish is top?

Touching a jellyfish is generally not advisable, as many species have tentacles that contain stinging cells, which can cause painful stings. Even if the top or bell of certain jellyfish appears harmless, it's best to avoid direct contact. Some jellyfish can still sting if they are dead or washed up on shore. Always exercise caution and admire jellyfish from a safe distance.
