(2)
Description: The Portuguese man-of-war, also known as Physalia utriculus, is a highly toxic species of jellyfish that floats underwater. Its striking bluish air bladder is a characteristic feature that signals the danger posed by its up to 10 meters long tentacles. The toxin mixture of the nematocysts can lead to serious health issues, such as respiratory arrest and heart failure. An unfortunate incident off the coast of Karachi illustrates the life-threatening effect of these jellyfish. Learn more about the fascinating yet dangerous Portuguese man-of-war and its way of life.
