Portuguese boat (Physalia physalis)

The second name for jellyfish is physalia. Although this is rather not even a jellyfish, but a whole colony of polypoid and medusoid individuals. The «bite» of a Portuguese boat is extremely dangerous and painful (sensations are compared to hitting the skin with a whip). The main risk is the systemic effects of the poison. In severe cases, intense pain is followed by fever, shock, and impaired heart and lung function, which can lead to death. Physalias are accustomed to moving in groups of up to 100 colonies, and sometimes in resorts they have to close entire beaches because of them!
