Blue bottle jellyfish is known for its long blue venomous tentacles. The species lives in the surface of the sea and are found in the Atlantic, Indian and Pacific Oceans. Jellyfish appear seasonally on the shores of southern islands during the monsoon season.
A bluebottle sting usually causes an immediate and severe pain. In some cases there will be nausea, vomiting, headache, pain in the abdomen and weariness. The toxins will be fatal once it leads to lesser circulation failure.
