(Browne, 1910)  Synonyms • Diplulmaris gigantea • Stygiomedusa fabulosa • Stygiomedusa stauchi Stygiomedusa gigantea, commonly known as the giant phantom jelly is a part of the monotypic genus of deep sea jellyfish, Stygiomedusa. This is in the Ulmaridae family.
 With only around 110 sightings in 110 years, it is a jellyfish that is rarely seen, but believed to be widespread throughout the world, with the exception of the Arctic Ocean.    The Monterey Bay Aquarium Research Institute's remotely operated underwater vehicles have only sighted the jelly 27 times in 27 years.
A study conducted by the Journal of the Marine Biological Association of the United Kingdom, focusing on four Stygiomedusa gigantea present in the Gulf of Mexico, revealed information regarding the wider distribution of this species.
The conducted search concluded that about 118 individuals reside throughout the Southern Ocean. S. gigantea is thought to be one of the largest invertebrate predators in the ecosystem.
 It is commonly found in the ocean's midnight zone,  reaching depths as deep as 6,665 metres (21,867 ft). [ citation needed] Contents • 1 Appearance • 2 Stygiomedusa gigantea • 3 Discovery • 4 Reproduction • 5 References • 6 External links Appearance [ edit ] S.
giantea has an umbrella-shaped bell that can grow up to 1 metre (3.3 ft). The bell's pliant tissue allows for the jellyfish to stretch 4 to 5 times its size, presumably to engulf their prey. Their four arms have a "paddle-like" or "kite-like" shape and can grow up to 10 metres (33 ft) in length. The arms grow in a "V" shape transversely,  with a wider base and tapering towards the ends. They do not have any stinging tentacles and instead use their arms to trap and engulf their prey which consists of plankton and small fish.
  From Browne's analysis of a collected S. gigantea, their jelly appears a red-orange color only when there is visible light.  However, since they dwell in the deep ocean, visible light does not penetrate far enough.
Thus, the giant jellyfish may appear "invisible" or glow orange very faintly in its surroundings, depending on the depth of the water. Furthermore, their bodies being made of either spongy tissue or jelly allow for the species to withstand the enormous deep ocean pressure of 5,800 pounds per square inch.
The circular stomach contained canals that travel to the surface of the sub-umbrella. It is inferred that the lower stomach is thick ensure the species has the strength to carry their long arms.
Its four genital openings were also small to avoid weakening the stomach.  Since there were no gastric pouches nor radial canals, the jellyfish was determined to be a part of the Ulmaridae family. [ citation needed] Behavior [ edit ] Known to be one of the largest invertebrate predators in the deep sea, the giant phantom jellyfish's typical prey consists of plankton and small fish. The S. gigantea tends to be more dominant in locations with a stygiomedusa gigantea productivity system, which in turn deters other predatory organisms, like fish, to high productivity systems (coastal, upwelling zones).
However, the jellyfish remains an important predator for the deep sea, often competing with squids and whales.  Larger S. gigantea have also been observed to be in the immediate vicinity of hydrothermal vents where large proportions of zooplankton are abundant. Stygiomedusa gigantea is in mesopelagic and bathypelagic depths. The further away from hydrothermal vents, the smaller the medusa are––indicating that zooplankton are an important resource for the species.
Due to this, the medusae are well off during early stygiomedusa gigantea to early summer when zooplankton biomass is enhanced.
 Evidence has been collected to support the first-ever documented symbiotic relationship for an ophidiiform fish, the Thalassobathia pelagica. Scientists have observed that the large umbrella-shaped bell of the S. gigantea provides food and shelter for the T.
pelagica, while the fish aids the giant phantom jelly in removing parasites. The S. gigantea 's jelly providing shelter for the Stygiomedusa gigantea pelagica is essential for the fish, considering the lack of shelter resources at such extreme ocean depths.
Studies to further support this symbiotic relationship have shown that the two species reassociate with one another even if separated. It was inferred that the Thalassobathia pelagica is able to find its way back to the giant phantom jelly due to neuromasts that increase the sensitivity of low-frequency water movements––of which the bell of the jellyfish emits.
 Discovery [ edit ] The first S. gigantea specimen, weighing in at ninety pounds, was collected in 1899, but it was not recognized as a species until 1959.  Despite having discovered only 118 individuals within 110 years (1899-2009), gelatinous mucus from the medusa have been found covering vents, indicating they may travel in swarms.
Similar large jelly Schyphomedusae were observed traveling in swarms off the West stygiomedusa gigantea of North America.
However, there are instances in which the species is spotted along, such as the S. gigantea identified at a depth of 1,200 meters in the San Clemente Basin just stygiomedusa gigantea of California.  The giant phantom jelly occurs all around the world with the exception of the Arctic Ocean. They are typically found 61ºN–75ºS and 135ºW–153ºE. In areas of high latitude in the Southern ocean, the depth at which the species may be found are at the mesopelagic and epipelagic levels.
However, in areas of mid to low latitude, the species are typically found at bathypelagic and mesopelagic levels.
This is due to the variability of the ocean's temperature and light distribution. [ citation needed] Reproduction [ edit ] Determining the reproduction of the S. gigantea is difficult considering how rare sightings are. It has been noted that young captured S. gigantea looked like an exact miniature' of the adult.  However, researchers have analyzed the jellyfish's structure and anatomy enough to understand how it may reproduce. The S. gigantea has four brood chambers that protrude into the stomach in folded narrow ridges and epithelium that covers the gastric side.
Its lower periphery has frills along the stygiomedusa gigantea, creating a band about 20 millimetres (0.79 in) high.  Above this band, there is a germinal line that forms a shallow groove with different epithelial cells that are more cubical in shape with large, rounded nuclei.  Irregular placement of the cells in small pits (small stygiomedusa gigantea of cells, similar to cyst) along the germinal line produce a multiplication of epithelial cells that create a deep invagination.
This is the first stage leading to the reproduction of S. gigantea. The cyst grows with a pointed end on the subumbrella side. As its size increases, it pushes out the brood chamber wall and into the cavity of the chamber.
Simultaneously on the opposite end, two outgrowths develop horizontally, making the cyst into a "T" shape.  This protrudes more and more as size increases, taking the brood chamber with it.
Eventually, this forms a thin membrane forms and the cyst enters the stomach cavity. [ citation needed] Within the cyst, a scyphistoma—a single developing medusa—forms and is now called a chorion. Once the chorion grows into about 2 millimeters long and 2-3 millimeters in diameter stygiomedusa gigantea teat-shaped distal ends (which are basal outgrowths), it begins to be pushed out of the chamber.
Within the chorion capsule, differentiation and formation begins. The inner epithelial wall is directly from the parent tissue and is pocketed into its distal tips that will eventually become the S. gigantea 's arms. As the stygiomedusa gigantea medusa grows, it takes the shape of the capsule.  In order to escape, the well-developed "baby" medusa will detach from the subumbrella wall where it was already slightly protruding.
It then exits through the gastric cavity and out the parent's mouth.  The baby medusa soon become free-swimming planules, then polyps or scyphistomae that reproduce asexually through budding or podocysts.
These are what become larval medusae that feed on plankton. Eventually, it will grow into the size of an adult. It is inferred that reproduction of S. gigantea is continuous with one parent estimated to produce fifty to one hundred medusa.

Moving in for a closer look, the submersible’s lights reveal the giant phantom jelly ( Stygiomedusa gigantea ). The bell of this deep-sea denizen is more than one meter (3.3 feet) across and trails four ribbon-like oral (or mouth) arms that can grow stygiomedusa gigantea more than 10 meters (33 feet) in length. MBARI’s ROVs have logged thousands of dives, yet we have only seen this spectacular species nine times. The first specimen of the giant phantom jelly was collected in 1899, but it was not until 60 years later that scientists recognized this as a new species.
Even now, scientists still know very little about this animal. MBARI’s observations of Stygiomedusa gigantea have helped illuminate its ecological role in the ocean’s depths. During an expedition to the Gulf of California, MBARI’s ROV Tiburon recorded a fish—the pelagic brotula ( Thalassobathia pelagica )—alongside a giant phantom jelly.
Researchers watched the brotula hover above the bell of its host and swim in and out of the jelly’s voluminous oral arms. The wide-open waters of the midnight zone offer little shelter, so many creatures find refuge in the stygiomedusa gigantea animals that are abundant in this environment.

To date, almost nothing is known about this rarely-encountered animal aside from detailed accounts of its physical description and sporadic sighting notes. It appears to have a wide distribution. It’s been collected in Antarctica and encountered during ROV operations in Japan, the Gulf of Mexico, Gulf of California. It has been encountered at depths between 750 meters down to 2187 meters in the Gulf of California and between 996m to 1747m in the Gulf of Mexico.
Specimens were collected in Antarctica at depths between 723 and 6669 meters. Stygiomedusa gigantea. Source: MBARI ROV footage. The broad, curtain-like arms are perhaps an adaptation that increases the odds of catching prey. It is generally assumed that prey item are difficult to locate stygiomedusa gigantea the deep sea and predators have evolved extraordinary means of keeping a hold on prey when it is encountered.
Stygiomedusa gigantea. Source: MBARI ROV footage. Remarkably, at least one animal might maintain a symbiotic association with this jellyfish. A fish, currently believed to be Thalassobathia pelagica, has been observed swimming near the bell of the jelly, though the exact nature of the relationship remains to be established. It’s possible that the relationship favors the fish more than the jelly, with the fish opportunistically feeding on scraps from the jelly’s feedings while also benefiting from a degree of protection-by-association.

This is one of only nine times that MBARI scientists have spotted the elusive creature across the institute’s many thousands of submarine dives.
"The giant phantom jelly was first collected in 1899. Since then, scientists have only encountered this animal about 100 times," MBARI said in a statement. The mouth-arms of the phantom jellyfish trail behind it like scarves in the wind.
(Image credit: © 2021 MBARI. ) Not much is known about phantom jellyfish, but scientists think it uses its mouth-arms, which stream like loose stygiomedusa gigantea in its wake, to ensnare unfortunate prey and winch them up to its mouth. The creature propels itself through the pitch-black depths of the ocean with periodic pulses from its faintly-glowing orange head. Before the deployment of remote controlled submarines like the one used for this expedition, scientists often used trawl nets to capture deep-sea creatures.
This was ideal for studying some creatures, but not deep-sea jellyfish, MBARI said. — In photos: The wonders of the deep sea — The 10 weirdest sea monsters — Photos: Deep-sea metropolis of octopuses "These nets can be useful for researching robust creatures like fish, crustaceans and stygiomedusa gigantea MBARI said. "But jellies disintegrate into gelatinous goo in trawl nets." Jellyfish are some of the most common creatures to be found in the deep sea, the compressible, squidgy jelly of their bodies enabling them to survive incredibly high pressures.
However, much about the brainless creatures remains to be discovered. It was once assumed that jellyfish were largely unimportant in deep-sea ecology, but a 2017 study by MBARI researchers showed that these cnidarians are actually among the most important predators in the dark depths, competing with cephalopods like squid, as well as fish and even blue whales for food.

gigantic (hence!) deep sea jellyfish that has been spotted in almost every ocean in the world. They really are enormous, with a bell that can reach over 1 metre (3 feet) across.
But that isn't what makes them REALLY big. Stygiomedusa gigantea makes them REALLY big are the four, 10 metre (32 feet) long drapes hanging off the bell. S. gigantea has no tentacles and no stinging cells. The curtains are grandly oversized oral arms which slowly waft behind the jellyfish's bell in a strangely surreal way.
It's like a mighty gust of wind blew through the window, sent the drapes flying and then FREEZE. It's thought that S. gigantea swims around with its oral arms flaring and uses them to basically absorb any small, planktonic creatures that get stuck to them. So next time your curtains are aflutter on a windy day, keep a close eye on them!
