The tentacles around the mouth of the jellyfish (Jellyfish) and the spine sac in the filamentous body contain venom. The toxicity varies depending on the type of jellyfish. When the venom contacts the human body, it can cause dermatitis and even systemic reactions.
(two) pathogenesis
When the jellyfish venom contacts the human body, it can cause dermatitis and even systemic reactions. The tentacles around the mouthpiece and the spine capsule in the filamentous body contain venom.
