Jellyfish

Chironex fleckeri, I am sorry to say, is wrong. Chironex feckeri is the species of the box jellyfish not the species. I am still trying to figure out the genus of the box jellyfish for a school project. I am sorry if this is no use to you but I just thought I would tell you that you go misinformation. Thank you for your time.

Brain corals are hemispherical or spherical in shape resembling a brain. They must me radially symmetrical organism.

Sponges do not have a mouth, a neural system or even any sensing organs. Still they have a variety of specialized cells, performing different tasks like pumping water, extracting and digesting particles from the water. A sponge may filter 10.000 - 20.000 times its own volume every day. Tiny hairs shimmer continuously to pump water through its internals. Sponges are responsible for the very important task of dissolving solid calcium and thereby enable mussels and others to reuse it to build their shells.

no there are other kinds of jellyfish that can kill humans like the Irukandji.

there is the stinger cell the outer cell and iner cells

" Jelly fish can reproduce two ways, both sexually and asexually. In asexual reproduction they bascially split or produce a bud which separates and swims off. When they reproduce sexually a male squirts its sperm into the sea which swim into the mouth of the female and fertilise her eggs. "

No, jelly fish do not fly.

im pretty sure 55 hours

yes. because a symmetry is when you draw a reflection so radial reflection is just if you draw the reflection but in the colors it has drawn.

Jellyfish live an average of about a year, although they can live much longer in captivity. Their lifecycle takes one year to complete. Juveniles are produced frompolyps in the spring and adults grow throughout the summer. Towards the end of the summer males and females mate and produce polyps, which grow and divide throughout the winter. In the spring the polyps start producing juveniles and the cycle repeats. This means that the swimming medusa life stage of jellyfish is only around for a few months during the summer. Jellyfish have delicate tissue, so they are usually damaged by the end of summer and most of them die. However, in captivity jellyfish can live much longer. It is not unusual for people to keep their pet jellyfish alive and healthy for 10 years or more if they feed them consistently.

as long as it is underwater and not icy yes.

Plankton.

I don't think they do...I could be wrong but I think all mollusks have a foot, visceral mass, and a mantle.

Comb jellies are somewhat different from true jellies (cnidarians). They lack stinging nematocysts and have developed other strategies to feed and protect themselves. Some of these include oral lobes to capture prey and sticky tentacles.

Well in low water in the ocean but they can come up to the surface.

Jelly fish are an amazing species. They kind of remind me of snakes but like flying. And shaky. They do not all have poison. but some do. If they sting you, you are going to feel it. It wont feel pretty either. Don't let that stop you from being you. I know you wanna be a famous surfer one day and you can be. Just buck up and get out there. Say "Hello jelly fish" and you'll achieve your destiny.

A jellyfish takes food in through its mouth which is located on the underside if its bell. Food is digested in a sac-like structure called a coelenteron or gastrovascular cavity. Waste material is passed out through the mouth.

The Cambrian Fossil Jellyfish; the oldest known jellyfish have been found in rocks in Utah. They are more than 500 million years old, according to scientific study reports. These jellyfish are also known as Cnidaria, which were on Earth for more than 580 million years. -wayoffline81 & Zappy22

Sexual. Like humans, they need the opposite sex to reproduce.

It stings people and that causes alots of death

true

because scientists did not know before and they thought that they were fish so they decided to call it like that.
