Moon jelly, a type of jellyfish found by dozens at Mission Bay during the warmer months, for some unknown reason does not sting, according to San Diego Lifeguards Sgt. Casey Owens.
Although, he warns of other jellyfish floating along the coast.
“I thought I saw a big plastic bag in the water,” said Nick Hischman, who narrowly missed getting touched by one. “As I got closer I saw it was big jellyfish and it had tentacles about a quarter inch thick spirally down.”
Sgt. Owens warns even if they appear to be dead on the sand they can still sting.
“Wave activity can break them up into little pieces so you won’t even see the jellyfish just feel the stings,” Sgt. Owens said.
If you do get stung the affect can range from a mild irritation to severe pain which can last for a couple hours or more.
The jellyfish along the California coastline are not deadly, according to Sgt. Owens.
“There’s some very strong jellyfish in other part of the world,” said Sgt. Owens. “We don’t have that here.”
To stop the pain, Owens suggests placing the stung body part in salt water. The worst thing a victim can do is pour fresh water on it – like a shower.
“When you put fresh water on them, they just react more and start to sting and the mechanism they use to sting starts to go off,” he said.
