The medusa stage of the coronate scyphomedusa Linuche unguiculata ('thimble jellyfish') can cause seabather's eruption.
Adult Linuche unguiculata medusae cause seabather's eruption just like that animal's larval form. This observation explains the wide seasonal incidence and the fact that lesions can appear on exposed skin.
