Jellyfish
“Jellyfish are free swimming, colorless, and range in size from a few inches to three feet in diameter”(California Beaches, 2009) says a Web site devoted to Southern California beaches. Though they are rare, the site reports that Jellyfish “sometimes appear during the summer months.”
The most recent time there was large amounts of jellyfish activity was in 2005 when over 100 people were stung over a weekend. This was a very rare occurrence, yet this proves that ocean-goers ought to be on the lookout. One warning sign swimmers should watch for is the occurrence of “red tide”, which happens when red plankton inhabit the area in large amounts, turning the water a reddish-brown color.
If you are or someone you know is stung by a jellyfish, find a lifeguard. They carry a vinegar solution which can take away some of the stinging feeling. If the stinging is accompanied by an allergic reaction, call 911 immediately.
