An example is seabather's eruption, which was recently found to be produced by injuries from swarms of Linuche unguiculata jellyfish planula larvae, off the southeast Florida Atlantic coast between midMay and mid-June.1 This particular disease was thought to be caused by many forms of marine life, including coelenterates.

Very few swimmers exhibited an eruption. One 6-year-old healthy boy had four 2- to 4-cm linear erythematous urticarial lesions across his torso and thigh.
