Jellyfish

     On the 8th grade class trip, we went to the aquarium, the beach, a fishing boat and the USS Lexington in Corpus Christi. Throughout the whole trip, jellyfish were popping up everywhere. One thing that I started to wonder was how do jellyfish sting you. I don't think jellyfish have brains so I was wondering how they knew when they are being hunted or attacked and if they know that they were in contact with a human. Apparently, jellyfish have cnidocytes full of venom called nematocysts. A touch of human skin or anything else will trigger this venom and target directly for the skin. To treat the sting, scientists recommend pouring saltwater on the sting. Before you rinse, make sure you get rid of all the jellyfish tentacles that can continue to sting you. Jellyfish tentacles do not need to be on the jellyfish in order to sting you. Just remember to be careful and keep an eye out for jellyfish when you are swimming in the ocean.
