Jellyfish

They look like blobs when washed up on the beach. But it's so Beautiful when you watch those documentaries on sea creatures... and the shots of Colorful jellyfish dancing gracefully in the deep blue sea.

Do you know?
~ They have been drifting through the world's oceans for more than 650 million years.
~ Jellyfish are not fish at all. They are invertebrates, relatives of corals and sea anemones (uh-NEH-muh-neez).
~ A jelly has no head, brain, heart, eyes, nor ears. It has no bones, either.
~ To capture prey for food, jellies have a net of tentacles that contain poisonous, stinging cells. When the tentacles brush against prey (or, say, a person's leg), thousands of tiny stinging cells explode, launching barbed stingers and poison into the victim.
~ Where there's water—from icy polar seas to tropical Pacific shores—there are jellies.
~ A jellyfish fires its poison whenever its tentacles brush against an object. In humans, the poison usually causes a sharp, burning sensation that may last from minutes to hours.
Useful Tips:
1. Take note of jellyfish warning signs posted on the beach.
2. Be careful around jellies washed up on the sand. Some still sting if their tentacles are wet. Tentacles torn off a jelly can sting, too.
3. If you are stung, wash the wound with vinegar or rubbing alcohol. Or sprinkle meat tenderizer or put a baking soda and water paste on the sting. Don't rinse with water, which could release more poison.
4. Lifeguards usually give first aid for stings. See a doctor if you have an allergic reaction.
