the fried egg jelly fish belongs in the scyphoza family.
jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species).
the fried egg jellyfish are in the class, true jelly fish.
fried egg jelly fish are in the semaeostomeae order.
freshwater jellyfish, any medusa, or free-swimming form, of the genus Craspedacusta, class Hydrozoa (phylum Cnidaria
the species jelly fish belong in is cnidaria.
Acraspeda. Cubozoa—box jellyfish. Scyphozoa—true jellyfish. Staurozoa—stalked jellyfish. some Hydrozoa—small jellyfish.
the oldest ancestors of the modern day jellies lived at least 500 million years ago, and maybe as long as 700 million years ago.
Their closest cousins include corals and anemones. “Corals, anemones, things we call hydroids, sea pens.
Jellyfish come from one of the oldest branches on the animal family tree, the phylum Cnidaria, which includes corals and anemones. Jellyfish were probably the first muscle-powered swimmers in the open ocean.
The body of a jellyfish exhibits radial symmetry and is divided into three main parts: the umbrella, the oral arms (around the mouth) and the stinging tentacles. They have an internal cavity, in which digestion is carried out. This cavity has a single aperture which functions both the mouth and the anus. the size of a jelly fish verys, Jellyfish come in all shapes and sizes. Most jellies range from less than half an inch (1 cm) wide to about 16 inches (40 cm), though the smallest are just one millimeter wide! The largest jellies are the Lion's Mane Jellyfish (Cyanea capillata), which on average are around 3 feet wide. The weight of a jelly fish can depend also if there small there going to weigh less. some jelly fish that are around 7 feet can get up to 440 pounds.
Most jellyfish are short lived. Medusa or adult jellyfish typically live for a few months, depending on the species, although some species can live for 2-3 years in captivity. Polyps can live and reproduce asexually for several years, or even decades. One jellyfish species is almost immortal.
The eggs in the females are large and globular, while the male gonads are shaped like sausages. Crossota jellies reproduce sexually and give “birth” to live young.

Most jellyfish stings cause relatively minor pain and irritation. Simpson said several factors could be causing the decline in stinging jellyfish, including this summer's cool weather and heavy rainfall. "The water temperatures have been below average for this time of year," he said.
there are some types of plants in a jelly fishes enviroment and they dont effect of a jelly fishes habitat.
These animals face threats from various sea and land creatures including sea anemones, swordfish, sea turtles, tuna, and penguins.
Recent research has revealed that the increases in jellyfish populations can be linked to human activity, too. As greenhouse gases trap heat on the planet, oceans are heating up — they absorb 93% of that excess heat. Unlike many marine species, jellies can thrive in warmer water with less oxygen.
Jellyfish can be found in saltwater and brackish or slightly salty water. Most jellyfish are found in coastal zones but some species live in deep-sea or near the surface in the pelagic zone of the open ocean. Jellyfish can be found in every ocean on Earth.
This species of jellyfish is generally found in Antarctica and the Antarctic Peninsula near the surface in continental shelf waters.
The creatures are an invasive species and are native to Australia and the Philippines, according to the National Invasive Species Information Center.
Generally speaking jellyfish should be fed daily, but jellies don't need food in the same way as we do – instead they use food for growth! So, if your jellyfish is getting too big, put him on a diet – feed once every couple of days, and you'll see him shrink in size.
Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. Jellyfish digest their food very quickly.
Some jellyfish are as tiny as a pinhead, so they can only feed on things like plankton, which are small, floating creatures. Larger jellyfish prey on bigger food sources such as fish, shrimp, and crab. its not hard for a jelly fish to find its food.
DAY 3
Jellyfish groups can go by three different names. A collection of jellyfish are called a "bloom," "smack," or "swarm.
They are food for a number of marine animals such as large fish and turtles. Even humans eat jellyfish. Jellyfish also provide habitat for many juvenile fishes in areas where there are not many places to hide. They can also protect the small fish from being eaten by predators with their stinging cells.
have discovered that jellyfish are providing habitat and space for developing larval and juvenile fish. The fish use their jellyfish hosts as means of protection from predators and for feeding opportunities, helping to reduce fish mortality and increase recruitment.
The biggest interaction with other organisms involves predation, both with jellyfish as the predator and the prey. Recall, jellyfish usually consume organisms such as zooplankton, copepods, cladocerans, larvaceans, and bivalves. They use their cnidocytes which eject nematocysts to catch and kill their prey.
There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs directly into the water. Under favourable conditions they will do this once a day, usually synchronised to dawn or dusk.
jelly fish typically have 1 mate and thats when the female puts out her eggs and a male jelly fish will come by and fertilize the eggs.
Usually, they peak in August or September. They are present all year long, but large blooms in warm waters combined with the right currents and wind conditions can bring them in the vicinity of beachgoers.
In this species, a male will use his tentacles to grab a female's tentacles; he will then drag her around for a while before pulling her in close to him. Next, he will produce and release a spermatophore (sperm packet), and use his tentacles to pass it to one of the females tentacles.
Theres no unique characteristics to helly mating.
Jellyfish have a stalked (polyp) phase, when they are attached to coastal reefs, and a jellyfish (medusa) phase, when they float among the plankton. The medusa is the reproductive stage; their eggs are fertilised internally and develop into free-swimming planula larvae.
The hydroids bud new jellyfishes, which are released at about one millimetre in size and then grow and feed in the plankton, becoming sexually mature after a few weeks (the exact duration depends on the ocean temperature.
An elementary nervous system, or nerve net, allows jellyfish to smell, detect light, and respond to other stimuli. ... This “radial symmetry” allows jellyfish to detect and respond to food or danger from any direction. Jellyfish have the ability to sting with their tentacles.
You can tell the male from the female by its sex glands. The males' sex glands are pink while the females' are brown. Moon jellyfish develop in four stages: larval, polyp, ephyrae and medusa. A female adult jellyfish produces eggs and holds them for about a month.
DAY 4
Among the predators of the jellyfish, the following have been identified: ocean sunfish, grey triggerfish, turtles (especially the leatherback sea turtle), some seabirds (such as the fulmars), the whale shark, some crabs (such as the arrow and hermit crabs), some whales (such as the humpbacks).
At high densities, jellyfish can seriously effect populations of zooplankton and ichthyoplankton, and may be detrimental to fisheries through competition for food with fishes and by direct predation on the eggs and larvae of fish.
It is not known if all jellyfish of this and other species carry similar bacteria or the relationship to each other. Their source, the role they play under other circumstances, and indeed whether the jellyfish were themselves diseased are also not known.
Common jellyfish is actually two species, scientists find: Researchers determine that US Atlantic sea nettle and the Atlantic bay nettle are individual species." ScienceDaily.
