The graceful Portuguese Man-of-War - a fascinating marine wonder (Physalia utriculus) (00016705)
(3)
Description: The Portuguese Man-of-War, also known as Blue bottle or Physalia utriculus, is a fascinating creature belonging to the genus of colonial jellyfish. Each Portuguese Man-of-War consists of a colony of polyps with various functions. Its striking, bluish shimmering gas bladder makes it easily recognizable, but the real danger lies in its tentacles, which can reach up to 10 meters in length. With up to 1000 cnidocytes per square centimeter, its stings are extremely dangerous. The venom, which acts directly on nerve cells, can cause muscle contractions, respiratory failure, and even heart failure. A personal experience off the coast of Karachi, Pakistan, illustrates the life-threatening effects of this captivating creature. Immediate medical attention is essential when coming into contact with a Portuguese Man-of-War.
