Invisible marine organisms episodically inflict nuisance cutaneous stings on oceanic bathers. 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.

Between December 26 and 28, 1994, from Boca Raton to Pompano Beach, Fla, numerous instances of minor cutaneous stings and irritations were reported during daylight hours. 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. At that time, small 1- to 2-mm-diameter, slightly opaque strips of coiled tissue with black dotted centers were also seen in the surf. Microscopic examination of these structures revealed fragments of tentacles containing bean-shaped spirocysts and
