Document Summary
Jellyfish and portuguese man-of-wars have long tentacles equipped with nematocysts. The tail barb of a stingray easily penetrates human skin and can do significant damage. For a bite, rip, or puncture caused by a shark, barracuda, eel, or seal: Flush the area with water under pressure. For a sting caused by jellyfish, portuguese man-of-war, sea anemone, or fire coral: For hawaiian box jellyfish and portuguese man-of-wars, soak in vinegar for 30 seconds. For jellyfish stings in north america and hawaii: Soak in non-scalding hot water for 20 minutes. Xylocaine can be applied on the affected skin. For a puncture caused by a stingray, scorpion fish, stonefish, starfish, or catfish: Soak in hot water for 30 to 90 minutes. When surrounded by air or water cooler than body temperature, the body experiences heat loss. If body temperature falls much below that, cold injuries can result. The body has two internal mechanisms to maintain body temperature.
