Portuguese man-of-war (Physalia utriculus) washed up on a beach. Also known as a bluebottle,this organism is a floating hydrozoan. It consists of a colony of four types of polyps with different functions. This polyp is the gas-filled float. It also has its tentacles trailing behind it (not seen) that inflict a painful sting. Although rare,in severe human cases the victim may suffer cardiovascular and respiratory collapse. Photographed at De Hoop Nature Reserve,South Africa | |
