Squishy
Our first practice in the English Channel was an experience of a lifetime. The temperature was 59 degrees and the waves were choppy. All of us were together fighting the waves and enjoying the group's company. During the swim, I felt a jellyfish inside my hand. The jellyfish felt very squishy hence the name of the blog. A lot of the other swimmers felt them also on their hands, arms, and other parts of the body. Fortunately, no one got stung. Our first time in the English Channel was enjoyable and we are prepared to swim on July 1st, which is our set time to swim.

Have fun! My aquarium friends tell me that the jellyfish in the channel are unlikely to sting until the water temperature is consistently above 65°.
ReplyDeleteSounds like lots of fun. All you need is some bread & peanut butter. Yummy!
ReplyDeleteGood Luck! Just came across this site.
ReplyDeleteMy husband and I were both collegiate swimmers. He actually swam the Channel as a relay in college. We just had our first daughter, Calais and named her after the town you will finish in!
i'll email the PDF to Jim ... in short topical lidocaine.

A series of tests were carried out with chemicals traditionally used to treat jellyfish stings e.g. acetic acid ammonia meat tenderizer baking soda and urea ... ... It was found that many of the chemicals traditionally used to treat jellyfish stings stimulated nematocyst discharge and did not relieve the pain. However there was immediate relief when a common anesthetic lidocaine was sprayed on the skin of testers in contact with jellyfish tentacles. Initial exposure of tentacle suspensions to lidocaine prevented the nematocyst discharge by subsequent exposure to acetic acid ethanol ammonia or bromelain. Thus lidocaine in addition to acting as an anesthetic on skin in contact with jellyfish tentacles inhibited nematocyst discharge possibly by blocking sodium and/or calcium channels of the nematocytes.
