Jellyfish are single organisms that are free swimming and capable of moving themselves through water. Siphonophores are a colony of single celled organisms and are ocean drifters, incapable of moving through the water on their own.

Is a siphonophore a jellyfish?
Jellyfish are single organisms that are free swimming and capable of moving themselves through water. Siphonophores are a colony of single celled organisms and are ocean drifters, incapable of moving through the water on their own.
Is siphonophore real?
The Praya dubia, or giant siphonophore, is an invertebrate which lives in the deep sea at 700 m (2,300 ft) to 1,000 m (3,300 ft) below sea level. It has been found off the coasts around the world, from Iceland in the North Atlantic, to Chile in the South Pacific.
Are humans siphonophores?
Siphonophores, then, have become extremely complicated organisms, just as we have, but in an entirely different way. Whereas we are made up of specialized cells that are arranged into tissues and organs, siphonophores are made up of specialized zooids precisely organized at the level of the colony.
Are siphonophores poisonous?
While rarely fatal to humans, their stings can be excruciating. Often, swimmers and divers don’t even notice the transparent animals until it’s too late. The tentacles can even sting if they’ve been separated from the main body or after the organism has died.
What do siphonophores do?
Meet the giant siphonophore Giant siphonophores, like all siphonophores, are a collection of highly specialized working parts. Some parts catch prey, others digest food, some parts reproduce and others direct the action by swimming. This siphonophore is bioluminescent — it creates its own light.
What does a siphonophore look like?
The majority of siphonophores are long and thin, consisting mostly of a clear gelatinous material. Some deep water species have dark orange or red digestive systems that can be seen inside their transparent tissues. Siphonophores are exceedingly fragile and break into many pieces under even the slightest forces.
How does a siphonophore eat?
Each polyp has a single tentacle that is 30 to 50 cm (11.8 to 20 in) long. On contact stinging cells (nematocysts) shoot “harpoons” of toxin into the victim that paralyze and even kill it. The meal is then transferred to the canals that carry it to the entire colony. All siphonophores are predatory carnivores.
Where does siphonophore live?
the deep sea
The majority of siphonophores live in the deep sea and can be found in all of the oceans. Siphonophore species rarely only inhabit one location. Some species, however, can be confined to a specific range of depths and/or an area of the ocean.
