Siphonophores are predatory carnivores. [4] Their diets consist of a variety of copepods, small crustaceans, and small fish. [4] Generally, the diets of strong swimming siphonophores consist of smaller prey, and the diets of weak swimming siphonophores consist of larger prey. [18]
Is a siphonophore a carnivore?
Siphonophores are predatory carnivores. Their diets consist of a variety of copepods, small crustaceans, and small fish. Generally, the diets of strong swimming siphonophores consist of smaller prey, and the diets of weak swimming siphonophores consist of larger prey.
How do siphonophores get their food?
Due to the lack of food in the deep sea environment, a majority of siphonophore species function in a sit and wait tactic for food. The gelatinous body plan allows for flexibility when catching prey, but the gelatinous adaptations are based on habitat. They swim around waiting for their long tentacles to encounter prey.
How many species of Siphonophora are there?
The Siphonophorae or Siphonophora, the siphonophores, are an order of the hydrozoans, a class of marine animals belonging to the phylum Cnidaria. According to the World Register of Marine Species, the order contains 188 species. Although a siphonophore may appear to be a single organism,...
Where do siphonophores live?
They mostly feed on larger prey. 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.
Are siphonophores poisonous?
Narration. Whales may be the most massive creatures in the world, but the longest animals are siphonophores. Some, like the Portuguese man of war, are among the most venomous.
What makes siphonophores unique?
Siphonophores take a very different developmental and evolutionary approach to becoming large, complex organisms. They also start with one body, but they grow by asexually producing many more small bodies that all remain attached.
How do siphonophores hunt?
Siphonophores spread out a curtain of stinging tentacles to snare all sorts of prey, including fishes, tiny plankton, and even other jellies. Siphonophores hunt using specialized branches to their tentacles called tentilla. The tiny tentilla are loaded with stinging cells for trapping prey.
Does a siphonophore have a brain?
There is no central brain—each creature has an independent nervous system, but they share a circulatory system. This frees the small bodies to pursue whatever they might devote themselves to. Some provide protection, some are responsible for eating, for reproduction, or for producing colorful glowing light.
How big is the biggest siphonophore?

How a siphonophore is born?
The pelagic siphonophore colony develops from a single fertilized egg. The egg becomes a protozooid that buds to form the different structures with their different functions. Polyps of some siphonophores become reproductive cells that contain sperm or eggs.
Do siphonophores have eyes?
Despite its abundance, its visual pigments have never been measured; their eyes are extremely small and they are too fragile for many deep-sea trawling operations.
Do siphonophores have predators?
It provides a very, very robust shelter.” In addition to dangling stinging tentacles, some varieties of siphonophore are totally covered with stinging cells to protect them from predators, chiefly the majestic ocean sunfish as well as leatherback turtles, which have fairly disturbing spikes in their mouths to keep ...
Do siphonophores have organs?
Within siphonophores, each body is highly specialized to serve a function such as swimming, eating, digesting, reproducing, and defending the colony. The zooid effectively acts as an organ, providing different services to the whole colony.
What does a siphonophore mean?
Definition of siphonophore : any of an order (Siphonophora) of colonial, free-swimming or floating, marine hydrozoans (such as the Portuguese man-of-war) that are mostly delicate, transparent, and colored and have zooids possessing specialized functions (such as feeding or locomotion) …
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.

Are jellyfish related to siphonophores?
Siphonophores belong to the Cnidaria, a group of animals that includes the corals, hydroids, and true jellyfish. There are about 175 described species. Some siphonophores are the longest animals in the world, and specimens as long as 40 meters have been found.
How do siphonophores feed?
Siphonophore Feeding Most siphonophores catch prey by putting out their long tentacles and waiting for something to bump into their tentilla. Think of a spider web which is also laced with stingers.
Is a siphonophore a carnivore?
Predation and feeding Siphonophores are predatory carnivores. Their diets consist of a variety of copepods, small crustaceans, and small fish. ... Similar to many other organisms in the phylum of Cnidaria, many siphonophore species exhibit nematocyst stinging capsules on branches of their tentacles called tentilla.
Is a siphonophore a predator?
Siphonophores, which are related to jellyfish, are deep-sea predators that prey on tiny crustacean and fish using the vast array of stinging cells on their tentacles.
Can a siphonophore sting?
Like the jellyfish, siphonophores sting with tentacles. ... and it's sting is excruciating. Even worse, it's stingers can break loose. and still do damage floating around on their own.
Meet the common siphonophore
This animal swims to the surface to feed and sets fine tentacles adrift like fishing lines. The tips resemble tiny shrimplike creatures — a tasty bait. The predator lies in wait, then reels in its prey.

Where are the smaller individuals located in a siphonophore?
The smaller individuals are concentrated towards the top of the siphonophore, and their function is turning and adjusting the orientation of the colony. Individuals will get larger the older they are. The larger individuals are located at the base of the colony, and their main function is thrust propulsion.
What phylum are siphonophores in?
Organisms in the order of Siphonophorae have been classified into the phylum Cnidaria and the class Hydrozoa. The phylogenetic relationships of siphonophores have been of great interest due to the high variability of the organization of their polyp colonies and medusae. Once believed to be a highly distinct group, larval similarities and morphological features have led researchers to believe that siphonophores had evolved from simpler colonial hydrozoans similar to those in the orders Anthoathecata and Leptothecata. Consequently, they are now united with these in the subclass Hydroidolina .
Why do siphonophores swim?
Due to the lack of food in the deep sea environment , a majority of siphonophore species function in a sit and wait tactic for food. The gelatinous body plan allows for flexibility when catching prey, but the gelatinous adaptations are based on habitat. They swim around waiting for their long tentacles to encounter prey. In addition, siphonophores in a group denoted Erenna have the ability to generate bioluminescence and red fluorescence while its tentilla twitches in a way to mimic motions of small crustaceans and copepods. These actions entice the prey to move closer to the siphonophore, allowing it to trap and digest it.
How do zooids reproduce?
Siphonophores are colonial hydrozoans that do not exhibit alternation of generations, but instead reproduce asexually through a budding process . Zooids are the multicellular units that build the colonies. A single bud called the pro-bud initiates the growth of a colony by undergoing fission. Each zooid is produced to be genetically identical; however, mutations can alter their functions and increase diversity of the zooids within the colony. Siphonophores are unique in that the pro-bud initiates the production of diverse zooids with specific functions. The functions and organizations of the zooids in colonies widely vary among the different species; however, the majority of colonies are bilaterally arranged with dorsal and ventral sides to the stem. The stem is the vertical branch in the center of the colony to which the zooids attach. Zooids typically have special functions, and thus assume specific spatial patterns along the stem.
Why do siphonophores emit light?
Like other hydrozoans, some siphonophores emit light to attract and attack prey. While many sea animals produce blue and green bioluminescence, a siphonophore in the genus Erenna was only the second life form found to produce a red light (the first one being the scaleless dragonfish Chirostomias pliopterus ).
How many nectophores are there in a calycophoran?
The nectophores pump the water back in order to move forward. Calycophorans differ from cystonects and physonects in that they have two nectophores and no pneumatophore. Since their origin, an increase in the number of zooid types has been observed in siphonophores.
What is the synonym for Calycophorae?
