The wounded area must be kept in hot water for 30-60 minutes. Call the Poison Center for more information. There are many species of jellyfish. They are usually almost colorless and therefore difficult to see. The bodies consist of a bell and many trailing tentacles.
Jellyfish are poor swimmers and usually are found drifting in the water.
In a strong current, jellyfish can be washed onto the shore, causing problems for barefooted people who aren't watching where they are walking. Jellyfish have stinging cells usually found on the tentacles, but sometimes in the bell. Injury can result from skin contact with any part of the jellyfish. Exposure causes pain, redness, itching, swelling, skin irritation and blisters. If exposed to a jellyfish, do not rinse the area with fresh water and do not rub the area.
