A siphonophore is unusual in that it is comprised of a colony of specialized, genetically identical individuals called zooids — clones — with various forms and functions, all working together as one.
How has the Portuguese Man O War fish adapted?
The Portuguese Man of War has developed many adaptations in order to survive in its marine environment. One such adaptation is its method of locomotion. It floats passively on the surface of the ocean and is directed by the wind, via the pneumatophore, and the current.
How does a man o war reproduce?
How does it reproduce? Scientists believe that man-of-wars spawn together in large numbers, with each colony (being either all male polyps or all female polyps) releasing gametes into the water to be fertilized. The resultant larvae then each go through asexual budding to produce a new man-of-war colony.

What did the Portuguese men of war eat?
Portuguese Men of War feed on a wide variety of soft bodied prey, including fish, fish larvae, cephalopods, and eel larvae. They are prevented from capturing hard bodied organisms due to the structure of their nematocysts. Like wise, larger fish, such as flying fish and mackerel, usually manages to escape the tentacles.
What is the function of the Portuguese Man o War?
Portuguese Man-o’-War. Other members of the colony perform the tasks of food capture and feeding. The long, trailing tentacles (dactylozooids) are armed with stinging cells that contain nematocysts. Nematocysts inject a barbed thread and paralyzing toxin to capture and subdue prey like small fish.

Specialized predators on the man-o’-war include sea slugs and snails that also float at the ocean surface.
