Interesting... was worth a shot.
Here's a tidbit of information I found from the Amercian Academy of Allergy Asthma and Immunology (AAAAI). Not sure if it's relevant or not, but thought I'd post it up anyway....
There is a reaction known as "seabather's eruption," a rash that happens after someone is exposed to ocean water and usually covers the area of the body covered by the bathing suit (although children may have reactions all over). According to a study in the New England Journal of Medicine, the rash may be caused by an organism that may be too tiny to see, but will eventually grow into an adult sea anemones called Edwardsiella lineata. Some sea anemones can hurt people with poisonous stings, but I'm not sure if this particular anemone does that. In any event, the researchers suspect that the tiny larval stage of this anemone may be what causes the rash.
