The stinging sea nettle (Chrysaora) is a genus of particulary large true sea jellies (Scyphozoa). The name may refer to the East Coast sea nettle (Chrysaora quinquecirrha), a species of sea nettle that inhabits particularly Atlantic estuaries. The name sea nettle may also refer to the West Coast sea nettle (Chrysaora fuscescens) (pictured to the right), another related species that is endemic to the Northeast Pacific Ocean. It is a common coastal species found along the west coast of North America from California to Alaska. The Atlantic sea nettle is a bell-shaped invertebrate, usually semi-transparent and with small, white dots and reddish-brown stripes. Sea nettles without stripes have a bell that appears white or opaque. The nettle's sting is rated from "moderate" to "severe" and can be pernicious to smaller prey; it is not, however, potent enough to cause human death, except by allergic reaction. While the sting is not particularly harmful, it can cause moderate discomfort to any individual stung. The sting can be effectively neutralized by misting vinegar over the affected area. This keeps unfired nematocysts from firing and adding to the discomfort.
