I have phobia for water so I don't even go near the ocean at all.The fact that some kids died because they were bitten by jellyfish is news to me.I never thought much of this gelatinous, undulating creatures called jellyfish..so I had to open my laptop to do a little research
The fact is that all jellyfish produce toxins but not every species is dangerous to man.Their are a couple thousand varieties worldwide but only a handful are deadly.
The box jellyfish are the most dangerous (they have 10 foot tentacle and the most potent venom).They are mostly found in waters off the coast of Australia.By contrast, others like cannonball jellies-tennis to soccer ball sized blobs that exist primarily in the golf of Mexico are not dangerous to humans.
Whether a jellyfish is dangerous or not,if you find yourself in an ocean and you are bitten by a jellyfish,get out of the water,carefully remove the tentacle with a towel or sand but don't use your hand to avoid further stinging.Contrary to popular belief,peeing on the area won't relieve the burn.Just soothe the pain with vinegar or a paste made of baking soda.See a doctor if you feel sick.
