Who Wins on Size? It's pretty obvious that the Blue Whale is the bigger apex predator in this fight.
Is deep sea gigantism real?
In the deepest and coldest parts of the ocean, sea creatures — mainly invertebrates, or animals without backbones — can reach gargantuan proportions. Squids, sea spiders, worms and a variety of other types of animals grow to sizes that dwarf related species around the world. The phenomenon is called gigantism.
Is a siphonophore bigger than a blue whale?
A giant siphonophore can grow to 130 feet (40 m) in length — longer than a blue whale.
Why are siphonophores considered to be one organism?
Because siphonophores function as multiple parts of a whole, they challenge the notion of individuality. Though the entire colony looks like one animal, it's tricky to classify siphonophores as one organism since they're comprised of so many different living individuals.

Where is the longest ocean creature?
An approximately 150-foot long siphonophore — possibly the longest ocean creature ever recorded — was recently discovered off the coast of Australia. Siphonophores are made up of tiny individual zooids, or clusters of cells that can clone themselves thousands of times and string together as one large, floating creature.
Where do siphonophores live?
However, most siphonophores exist as active swimmers in the open ocean.
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 ).
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 .
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?
Calycophorae. Cystonectae. Physonectae. Synonyms. Siphonophora Eschscholtz, 1829. Siphonophorae (from Greek siphōn 'tube' + pherein 'to bear') is an order of Hydrozoans, a class of marine organisms belonging to the phylum Cnidaria. According to the World Register of Marine Species, the order contains 175 species.
Where are nectophores located?
The nectophores of these organisms are located in the nectosome where they can coordinate the swimming of colonies. The nectophores have also been observed in working in conjunction with reproductive structures in order to provide propulsion during colony detachment.
What is the siphonophore?
In fact, none of its parts could function on their own. Each siphonophore is actually a colony of individual parts, called “zooids”, which are produced as the siphonophore grows, and stay connected together. Some form rope-like chains that can grow longer than a whale.
Where are siphonophores found?
Scientists have found over 175 species of siphonophores, in habitats ranging from near-coastal regions to the ocean twilight zone and the sea floor. Deep water species are often dark orange or red in color, and are bioluminescent— glowing green, blue, and sometimes red—a function that likely attracts prey.
What do siphonophores use to trap their prey?
Siphonophores use their numerous tentacles to sting and trap their prey, injecting a toxin to incapacitate their prey. You may be familiar with this if you’ve ever touched a Portuguese Man O’ War! These traits often lead people to confuse siphonophores with their jellyfish cousins—but they are a distinctly different group.
What is the name of the colony of individual parts of a siphonophore?
In fact, none of its parts could function on their own. Each siphonophore is actually a colony of individual parts, called “zooids”, which are produced as the siphonophore grows, and stay connected together.

What is the name of the giant siphonophore?
The Giant Siphonophore, known by its scientific name Praya dubia in the first Endless Ocean game, is a species of siphonophore found in both Endless Ocean and Endless Ocean: Blue World .
How long is the Praya?
Their bodies can reach lengths of over 130 feet and are extremely long and thin. Technically, this species is actually a type of plankton. Though most people think of plankton as being microscopic, the scientific definition is any creature that passively drifts along with the current. As such, the Praya dubia fits the classification, despite its enormous size.”
Why does a siphonophore burst?
This odd manner of perishing is because its skeleton is hydrostatic, meaning that it is essentially held together with water pressure. This means that comparatively low water pressure will cause it to fall apart.

With a body length averaging out at 130 feet (40 meters) in real life, these creatures are the second-longest sea organism out there - the longest being a creature called the Bootlace Worm, which doesn't appear in either game.
What is the function of a colony?
Each link of the chain has a specific function, such as feeding, reproduction, attack, or defense, and takes on a form that suits that function.
Is a siphonophore harmful?
Though this creature is not harmful to the player, they are capable of delivering stings to their prey in order to paralyze and then consume it. In real life, it is unknown if these stings are capable of harming humans. When brought to the surface, a giant siphonophore will burst.
Where to find the Zahhab?
Two are found in the Zahhab Region Depths during both the daytime and the nighttime, only in the South Crevasse. An easy spot to look for them is near the Southern Cavern. However, they are reportedly easier to find at night, and they are also only able to be seen after the cutscene introducing them has triggered, which only occurs at night. As such, it would be wiser to search for them after the sun has set.
