Riply's Aquarium Sea Nettle Jelly Fish
Downtown Gatlinburg Tenn
Sea Nettles are equipped with a number of nematocysts along their oral arms and tentacles. These nematocysts are like capsules with a coiled thread inside it, which is lined with barbs along its length. The thread contains powerful paralyzing toxins within itself. When a sea nettle comes in contact with any hard surface and pressure is applied to the tentacles, these nematocysts get activated and the thread starts uncoiling. They get fired into the surface in its contact and inject their powerful venom into it.
