Jelly-Fish

There are various jelly-fish in the waters of Fire Island. Whereas in some parts of the world, like Australia, jelly-fish can be a serious health hazard, most jelly-fish in these parts are harmless. There is at least one exception: the lion's mane jelly-fish (graphic), a species that has a one-year life span and comes to maturity mid-summer. They derive their name from their crowns of red and orange-tinted tentacles. Warm weather increases the number of lion's main. Some experts say (and others deny) that low rainfall (which increases salinity at least in bays and sounds) is also a factor; we doubt that this is a factor in the ocean waters off Fire Island. Lion's mane, which can grow to two feet (not counting the tentacles of up to ten feet) can cause serious stings. They can even cause temporary blindness, so it is a good idea to wear goggles.

Stings on the skin should be treated with ammonia or vinegar. If only water is available, use salt water, not fresh. But if the eyes are involved, or if one is allergic, one should seek medical help. One can have skin irritations simply from swimming in waters inhabited by the jellyfish, or from handling one on the beech. Medical advice.
