The jellyfish you said is poisonous. I don't know if you only have fresh jellyfish. If it is, the average jellyfish will be toxic and hurt people when they are alive. The species of jellyfish are different, so the degree of toxicity is different. Generally, the jellyfish silk we eat is the ordinary jellyfish and sand jellyfish, which are not toxic in themselves. After professional processing, they are not toxic at all. You can eat it safely.
