Pelagia noctiluca (Forskal)

With its 10-15 cm body size, mushroom shape and 8 small extensions hanging from its body and 4 big extensions around the mouth, Pelagia noctiluca looks pleasant. However it is a poisonous and dangerous species of jelly fishes. Due to its phosphorescence feature, it spreads mild amount of light under the sea. They occur till to the 50 m. Its color can change from reddish yellow to purple. These animals particularly occur in the Aegean and Mediterranean coast, especially during the summer session. Its’ extensions have burning capsules and in the case of a strike, it can hurt. These extensions can be 50cm long so we should stay away from them. If you touch the animal, your body can get swollen and rushes will occur soon. Also it causes a burning sensation as well as a fewer. If this is the situation, swollen or hurt issue should be washed with lemon or vinegar without wasting any time. Don’t scratch or press the wound. If pain and swelling continue, you should go to the nearest health center.

Rhopilema nomadica

Rhopilema nomadica is not known with detail for our coasts. Its’ outlook reminds us a gong and It has no extensions. Burning capsules are occupied on the mouth and around the umbrella. This species came to our seas from the Suez Canal and feed with planktons. Rhopilema nomadica can reproduce both sexual and asexual thus it has a high potential of reproduction. Therefore, in short periods and especially from June to September, it can be seen more and it creates a potential danger for swimmers, fishermen and divers.

Chrysaora hysoscella

Burning capsule cells explode when it touches the skin and release their toxins which eventually cause burning sensation and itchiness. After itchiness, pain and rushes take its place. Blister and bleeding can be seen. Even if it is thought that this pain can go away with scratches and massages, it can cause asthma, nausea and stomach cramp in some people. If this jelly fish touches your skin, you should not scratch and massage it. If there are more unexploded burning capsules, a towel should be used to clean the skin. Washing the burning part with fresh water is a wrong way to solve the problem because it will explode the capsules which were not exploded yet. Cleaning the area that jelly fish stroke with ammoniac or vinegar can ease the relief. In serious injuries, you should see the doctor; otherwise it could cause more serious consequences.
