Cnidarians are aquatic animals belonging to the phylum Cnidaria. Common cnidarians include to jellyfish, sea anemones, corals and the Portuguese Man o' War. Questions about all species of cnidarians can be directed here.
Reidi Seahorses, Coral beauty angelfish, Fire Coral and many more types of coral, algea and more
Coral are very simple organisms, so they have no specialized  structures for removing waste. Instead, inside the coral tissue are  organisms called zooxanthellae that use the coral's waste for  photosynthesis.
Its diet consists of zooplankton, including  copepods, larval fish,  ctenophores,  salps, other jellies, and fish eggs
jellyfish dont actually lay eggs as such but when they reproduce  they produce an actual seperate animal called a polyp. these polyps  are like tiny anemones which live, grow and reproduce indepently.  the polyp will live for many years producing new jellyfish  periodically. when the conditions...
If you got stung by a sea anemone, normally, blisters would appear  where the sea anemone had contact on your skin.
Are bacteria sentient? No, they have no free will. Neither do Jellyfish. They cannot choose which direction to go, they simply go... So no they are not sentient. They have no brain and are unable to think of such thoughts, or think at all for that matter. They perform a task and that is all. BUT...
Boaters can protect coral by dropping their anchors on sandy  patches of sea bed.
Yes they do they wait about a min. to get back in the water or if  they don't they die
If the seabed is destroyed, the coral cannot get nutrients to live.
Yeah they do. That's how they eat.
The Great Barrier Reef is the largest coral reef ecosystem on earth  and one of the best managed marine areas in the world. At 348 000  square kilometres, the Reef is one of the richest and most diverse  natural ecosystems on Earth.    The unique qualities of this property were recognised in...

Herd the fish into a wall. 
The lions mane jellyfish was first discovered in 1870 when therewas one found washed up on the shore at Massachusetts Bay.
Florida or Hawaii or the Bahamas.
Hydra from greek mythology?
The Great Barrier Reef is in the South Pacific; specifically, it  is in the Coral Sea, which lies off the northeast coast of  Australia. It runs roughly parallel to the coast of Queensland. 
They don't have fins, they just go with the waves.
Jellyfish don't bite. They sting. If you don't get any treatment,  the STING will kill you in a day or two, slowly paralyzing you as  it goes.   Also, Man o' war isn't a fish or a jellyfish. A man o' war isn't an  individual organism. It's a colony of four different species of  microorganisms...
Tuna, Shark, Swordfish, Sea turtles, and one species of Pacific  salmon.
Jellyfish have a mouth that they place food into. Their bodies  aren't very complex but they do have a stomach and intestines. They  are carnivores which means that they eat other living creatures.  They tend to rely on the current of the water and the wind to help  them find food. They trap...
probably - depends on what the wage is
It's phylum is Cnidaria .
While jellyfish stings are painful, most are not emergencies. Expectpain, red marks, itching, numbness, or tingling with a typicalsting. But stings from some types of jellyfish - such as the box jellyfish (also called sea wasp) - are very dangerous , and can even be deadly .
Cnidarians have a gastrovascular cavity with one opening. They pull in food (smaller animals) with their stinging tentacles. In the cavity, enzymes break down the food. Nutrients diffuse directly to the body and waste is expelled out of the opening. Actually, the nutrients do not diffuse correctly...
Extracellularly in a digestive cavity.
Go get a life and don't try to cheat by looking answers up on the computer.
I am not sure if this is what you are asking but, The Great Barrier  Reef is off the east coast of the Queensland mainland in Australia.  It is part of the World Heritage List which, in a nutshell, means  that it is a protected area. You can learn more about it at either  of these sites. First,...
Pollution in the water.Also people pouring bleach into the water to catch fish.
  Various types of jellyfish,octipusus,dolphins,clownfish,giantclams,sea urchins and of course,coral!   salty, warm, shallow waters of coasts where there's LOT'S of sunlight!
Yes. They live in large groups in the Atlantic, Pacific, and Indian warm parts ocean. There have been sightings of portuguese man of wars being washed up together on the shores.
Well, there are a lot of limiting factors, but one I do know is: if there is an over abundance of fish and sea animals, the water will become less clear. Then the bacteria will start to die off, thus, killing the coral reefs, which will mean the fish and other sea life will have to find a different...
  they release the fetilized eggs out their mouth into the ocean
Very interesting question! The body of a jellyfish is made of 3  different layers: the epidermis (the skin), a middle layer called  the mesoglea (the "jelly part" that give the jellyfish a  see-through appearance), and an inner-layer called the gastrodermis  that connects these other layers with...
Jellyfish and corla belong to the Cnidaria phylum.
  Fish need it for food, the soil needs it for clean-up, and plants need it for filtering soil.
Even beached and dying jellyfish can still sting when touched. In  2010, at a New Hampshire beach, pieces  of a single dead lion's mane  jellyfish stung between 125 and 150 people.
Mainly squid. Sea Turtles and the bearded goby fish also eat jellyfish.
lives for 8 years in aquariums but the actual life span isnt known
Invertebrate. They have no backbone. Yes. All jellyfish species are invertebrate because they lack spines.
There is no huge coral formation on the north coast of Australia.  The Great Barrier Reef is a 2300 km long coral reef off the  northeastern coast of Australia.
  To find out how it grows reproduces the effects it has on it surroundings the same reasons scientists look at any thing. That their job studying things.
Because they were created that way
The gastrovascular cavity is where cnidarians digest their food.  The phylum cnidaria has over 10,000 species that live exclusively  in aquatic and mainly marine environments.
because the nutrents in the coral
The Great Barrier Reef is along the coast/shore of Queensland,  Australia.
jellyfish live in really deep oceans and lakes and rivers in Australian and also mostly in north America . thank you and have a nice day
A hydra is an invertebrate animal.
The Predators of the Nomura Jellyfish are: -Humans-Sunfish-Swordfish-Leatherback Turtles-TunaNomura Jellyfish sometimes eat each other, when very hungry.Nomura Jellyfish eat Zooplankton.:-) :-)
Jellies have one bodily orifice and they use it for everything.
A group of jellyfish is sometimes called a bloom or a swarm.
The Great Barrier Reef is being adversely affected through human  activities. The dumping of thousands of tonnes of toxic solid  wastes in oceans and the release of lethal chemicals in the seas,  leads to changes in the natural conditions prevalent. Moreover,  thermal power plants release large...
There are a total of 82 species of coral as of February 12th, 2010
sea pens, blue corals, soft corals and sea fans.
coral bleaching effects the reef . this occurs when the algae leaves the reef and it loses color and dies off . Another reason is tourist attractions. tourists come with their drinks and boats and pollutes the water . hope it helps..
fertilization in hydra in internal as well as external
It is an icon because it is very large and beautiful. Also, a lot of ppl visit it every day.
Most of the time Cape Coral stays in the 80s and 90s.
The crackling sounds are usually made by snapping shrimps.
1. it's an egg2. it cracks up3. it looks like a letter Y and walks4. it becomes a flat jellyfish5. it folds up and becomes a jellfish
according to my views it is very difficult to finding the sexof jellyfish but if we will try to ought with the help of net so wecan find the sex
The people of the area speak mainly English. The sea life in the reef probably speaks a dialect of fish.
sea anemone sea wasps sea jellies
no they are invertebrates
jelly fish can lay eggs or give birth it depends on the  different kind of mother and how much sperm she gets most jelly  fish lay 1 egg on something like sea weed or coral . then the one  egg makes clones of them self and they all stick togather. if your  going to a salt water beach and you...
Jellyfish have an absolutely unique feature. This is that they can  reversibly change from male to female and vice versa. They are  motile, i.e., medusa form.   They depend on food and nutrition through a method called  'filter-feeding'.   They live in deep seas.

Algae are in a symbiotic relationship with coral. Parrotfish, butterfly fish, angelfish, sea slugs, snails, worms and the crown-of-thorns starfish all eat coral.
