Portuguese man-of-war
Physalis species
Although it resembles a jellyfish, the Portuguese man-of-war is actually a colony of sea animals. Mainly found in tropical regions; however, the Gulf stream current can carry it as far as Europe. It is also found as far south as Australia. The floating portion of the man-of-war may be as small as 15 centimeters (6 inches), but the tentacles can reach 12 meters (40 feet) in length. These tentacles inflict a painful and incapacitating sting, but it is rarely fatal.
