► Vicious Beauties - The Secret World Of The Jellyfish (Full Documentary, HD)

The Lion’s mane jellyfish is the largest known species of jellyfish in the world. It has feet long, including the tentacles. They range in a vast variety of colors, sizes, and shapes. That is why it can be hard for the average person to know what they just saw was in fact a Jellyfish. Jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about described species, or of the class Cubozoa (approximately 20 species). Learn more about the characteristics and natural history of jellyfish in this article. Jellyfish are becoming the next trend in ornamental aquariums and Jellyfish Art is the leader in supplying live jellyfish and their specialized aquariums and products. Their mesmerizing forms and soothing movement create living works of art. Jellyfish aquariums are a new kind of interior decoration, sources of light and life that become the.

The order Rhizostomeae includes some 80 described species. In these jellyfish the frilly projections oral arms that extend down from the underside of the body are fused, obliterating the mouth and forming a spongy area used in filter feeding.

Marginal tentacles are lacking, and the gelatinous bell is firm and warty. In species whose life cycles are known, there is a typical benthic bottom-dwelling scyphistoma stage.

Most members of the order are vigorous swimmers. Species of Cassiopea , the upside-down jellyfish, however, swim infrequently and sit inverted in tropical shallows, exposing their photosynthetic symbiotic algae to sunlight.

The group Rhizostomeae is found mainly in shallow tropical to subtropical seas in the Indo-Pacific region, but members of the genus Rhizostoma, also called football jellyfish, often inhabit cooler waters, and Cotylorhiza is common in the Mediterranean.

The fourth order, Stauromedusae , comprises some 30 described species of nonswimming, stalked jellies. These species occur chiefly in cooler waters.

They are goblet-shaped and fixed by a basal stalk; the mouth is situated at the upper end. Ranging from 1 to 10 cm 0. Some species can detach and resettle.

Stauromedusae usually feed on small marine animals and live for several years. Development is direct from a larva into an adult.

The polyp stage is suppressed. A few species such as Aglaura hemistoma are omnivorous, feeding on microplankton which is a mixture of zooplankton and phytoplankton microscopic plants such as dinoflagellates.

Other species of jellyfish are among the most common and important jellyfish predators. Sea anemones may eat jellyfish that drift into their range.

Other predators include tunas , sharks, swordfish , sea turtles and penguins. Once jellyfish have become dominant in an ecosystem, for example through overfishing which removes predators of jellyfish larvae, there may be no obvious way for the previous balance to be restored: they eat fish eggs and juvenile fish, and compete with fish for food, preventing fish stocks from recovering.

Some small fish are immune to the stings of the jellyfish and live among the tentacles, serving as bait in a fish trap; they are safe from potential predators and are able to share the fish caught by the jellyfish.

Jellyfish form large masses or blooms in certain environmental conditions of ocean currents , nutrients , sunshine, temperature, season, prey availability, reduced predation and oxygen concentration.

Currents collect jellyfish together, especially in years with unusually high populations. Jellyfish can detect marine currents and swim against the current to congregate in blooms.

Jellyfish may also benefit from saltier waters, as saltier waters contain more iodine , which is necessary for polyps to turn into jellyfish.

Rising sea temperatures caused by climate change may also contribute to jellyfish blooms, because many species of jellyfish are able to survive in warmer waters.

When the phytoplankton die, they may create dead zones , so called because they are ahypoxic low in oxygen. This in turn kills fish and other animals, but not jellyfish, [80] allowing them to bloom.

They reproduce rapidly; they prey upon many species, while few species prey on them; and they feed via touch rather than visually, so they can feed effectively at night and in turbid waters.

Some jellyfish populations that have shown clear increases in the past few decades are invasive species , newly arrived from other habitats: examples include the Black Sea , Caspian Sea , Baltic Sea , central and eastern Mediterranean , Hawaii , and tropical and subtropical parts of the West Atlantic including the Caribbean , Gulf of Mexico and Brazil.

Jellyfish blooms can have significant impact on community structure. Some carnivorous jellyfish species prey on zooplankton while others graze on primary producers.

High density jellyfish populations can out compete other predators and reduce fish recruitment. During blooms, jellyfish significantly alter the nutrient availability in their environment.

Blooms require large amounts of available organic nutrients in the water column to grow, limiting availability for other organisms.

However, the low carbon availability shifts the process from production to respiration creating low oxygen areas making the dissolved inorganic nitrogen and phosphorus largely unavailable for primary production.

These blooms have very real impacts on industries. Jellyfish can out compete fish by utilizing open niches in over-fished fisheries.

Power plants have been shut down due to jellyfish blocking the flow of cooling water. Jellyfish form a component of jelly-falls , events where gelatinous zooplankton fall to the seafloor, providing food for the benthic organisms there.

Most jellyfish are marine animals, although a few hydromedusae inhabit freshwater. The best known freshwater example is the cosmopolitan hydrozoan jellyfish, Craspedacusta sowerbii.

It is less than an inch 2. Although most jellyfish live well off the ocean floor and form part of the plankton, a few species are closely associated with the bottom for much of their lives and can be considered benthic.

The upside-down jellyfish in the genus Cassiopea typically lie on the bottom of shallow lagoons where they sometimes pulsate gently with their umbrella top facing down.

Even some deep-sea species of hydromedusae and scyphomedusae are usually collected on or near the bottom. All of the stauromedusae are found attached to either seaweed or rocky or other firm material on the bottom.

Some species explicitly adapt to tidal flux. In Roscoe Bay , jellyfish ride the current at ebb tide until they hit a gravel bar , and then descend below the current.

They remain in still waters until the tide rises, ascending and allowing it to sweep them back into the bay. They also actively avoid fresh water from mountain snowmelt, diving until they find enough salt.

Jellyfish are hosts to a wide variety of parasitic organisms. They act as intermediate hosts of endoparasitic helminths , with the infection being transferred to the definitive host fish after predation.

Some digenean trematodes , especially species in the family Lepocreadiidae , use jellyfish as their second intermediate hosts.

Fish become infected by the trematodes when they feed on infected jellyfish. Jellyfish have long been eaten in some parts of the world.

Jellyfish are also harvested for their collagen , which is being investigated for use in a variety of applications including the treatment of rheumatoid arthritis.

Aristotle stated in the Parts of Animals IV, 6 that jellyfish sea-nettles were eaten in winter time in a fish stew. In some countries, including China, Japan, and Korea, jellyfish are a delicacy.

The jellyfish is dried to prevent spoiling. Only some 12 species of scyphozoan jellyfish belonging to the order Rhizostomeae are harvested for food, mostly in southeast Asia.

Traditional processing methods, carried out by a jellyfish master, involve a to day multi-phase procedure in which, after removing the gonads and mucous membranes , the umbrella and oral arms are treated with a mixture of table salt and alum , and compressed.

Processing makes the jellyfish drier and more acidic, producing a crisp texture. Freshly processed jellyfish has a white, creamy color and turns yellow or brown during prolonged storage.

In China, processed jellyfish are desalted by soaking in water overnight and eaten cooked or raw. The dish is often served shredded with a dressing of oil, soy sauce, vinegar and sugar, or as a salad with vegetables.

In Japan, cured jellyfish are rinsed, cut into strips and served with vinegar as an appetizer. Pliny the Elder reported in his Natural History that the slime of the jellyfish "Pulmo marinus" produced light when rubbed on a walking stick.

In , Osamu Shimomura extracted green fluorescent protein GFP and another bioluminescent protein, called aequorin , from the large and abundant hydromedusa Aequorea victoria , while studying photoproteins that cause bioluminescence in this species.

The genetic engineering technique fuses the gene of interest to the GFP gene. The fused DNA is then put into a cell, to generate either a cell line or via IVF techniques an entire animal bearing the gene.

In the cell or animal, the artificial gene turns on in the same tissues and the same time as the normal gene, making GFP instead of the normal protein.

Illuminating the animal or cell reveals what tissues express that protein—or at what stage of development. The fluorescence shows where the gene is expressed.

Jellyfish are displayed in many public aquariums. Often the tank's background is blue and the animals are illuminated by side light, increasing the contrast between the animal and the background.

In natural conditions, many jellies are so transparent that they are nearly invisible. They depend on currents to transport them from place to place.

Professional exhibits as in the Monterey Bay Aquarium feature precise water flows, typically in circular tanks to avoid trapping specimens in corners.

They have a live "Jelly Cam". Jellyfish are armed with nematocysts. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom , [] but only some species' venom causes an adverse reaction in humans.

Researchers described these as "self-propelling microscopic grenades" and named them cassiosomes. The effects of stings range from mild discomfort to extreme pain and death.

Stings may cause anaphylaxis a form of shock , which can be fatal. Jellyfish kill 20 to 40 people a year in the Philippines alone.

Jellyfish in large quantities can fill and split fishing nets and crush captured fish. Jellyfish travel guide from Wikivoyage. From Wikipedia, the free encyclopedia.

Soft-bodied, aquatic invertebrates. This article is about the aquatic animal-form. For similar animals, see gelatinous zooplankton.

Experts believe that this is why the Jellyfish has been able to survive through harsh conditions including pollution in the ocean waters where they live.

However, that lifespan is also quite short. The longest that any of the species survive is up to 6 months.

For others though they only live for a few short hours. The Turritopsis nutricula is an immortal jellyfish because it can revert to the polyp stage after becoming sexually mature.

The fast pace of their life from start to finish is something that experts continue to explore in great detail. They are committed to finding out all they can and sharing it with the public.
