The article “Health Issues for Surfers” (June 15, 2005, page 2313) contained an error in the figure legend for Figure 3, which described a jellyfish. The figure legend incorrectly described the jellyfish depicted in the figure as a box jellyfish (Carybdea alata), which is indigenous to American waters. However, the jellyfish shown was a Chironex fleckeri, which is indigenous to the South Pacific. The correct figure legend should have been, “A number of different types of box jellyfish exist, all displaying a characteristic bell with tentacles arising from the corners. Although Carybdea alata may be encountered in Hawaii, an even more venemous variety, Chironex fleckeri, shown here, is found in the South Pacific.” The online version of this article has been corrected.
