Imagine you are playing in the ocean with your friend. You look down and see an orange mushroom shaped fish right below you. It is about a foot long and is drifting up towards you. Your mind races to find out what it is. All the sudden you notice it is a… JELLYFISH!!! You start to swim as fast as you can, but you are not fast
enough. The jellyfish grabs you and stings you with its tentacles. You are
rushed to the
Color Jellyfish come in a big variety of colors. They are white, blue, pink, yellow, green, purple, red, orange, and striped. Each one of those colors represents the same thing. They are all bright colors and tell their enemies that they are dangerous fish. Tentacles The jellyfish’s tentacles look just like cooked noodles. The tentacles hang from underneath the jellyfish’s body. They can be as long as 1 cm to 120 feet long. That is longer than a basketball court! Some jellyfish have more tentacles than they do body. Other jellyfish only
have 1 cm long tentacles. The tentacles on a jellyfish are around the mouth.
That is because when jellyfish grab their prey with their tentacles that sting
them. After jellyfish sting their prey the jellyfish will pull their prey up to
their mouth with their tentacles so that they All jellyfish have a different amount of tentacles. They could have a few tentacles or as any as 800. That’s a lot! Every tentacle has a stinging cell. The stinging cell is located at the top of the tentacle. That is what makes the jellyfish able to sting their prey. When the jellyfish’s food swims by, it will touch the fish with its tentacles. That automatically kills the fish. When a jellyfish touches a person with their tentacles they will sting the person. If the jellyfish isn’t poisonous then the person won’t die. If the jellyfish is poisonous then the person might die. Size Jellyfish can be as small as a grape or as big as a bed. It depends on what kind of jellyfish it is. If it is a box jellyfish and it is full grown it will be 4 meters long. If it is an umbrella jellyfish and it is full grown then it will only be about 1 inch long. Body There are two layers in a jellyfish. There is an outer layer and an inner Jellyfish have no skeleton. Jellyfish don’t have bones, which means they can move any part of their body any way they want. Shape Jellyfish come in three different shapes. They either come in a cup, bowl, or
parachute shape. A cup shaped jellyfish is when the jelly like skin is frayed
and is curved to make a cup. A bowl shaped jellyfish is when the jelly like
skin
is round and curves to make a bowl. Finally, a parachute shaped jellyfish is
when the tentacles are a little bit longer than the body and fayed out How do jellyfish move? A jellyfish moves like an umbrella. The jelly like skin opens and lets water in. Then the jellyfish closes its jelly like skin and pushes all the water out. When the happens the jellyfish will shoot up just like a rocket ship. How long do jellyfish live? Jellyfish tend to live for about one year. If jellyfish don’t live for about one year that is probably because another fish, turtle, or bird eats it. Another way they could die early is if they aren’t in salt water. Jellyfish have to be in salt water to be able to live. Most sea animals are decreasing from the amount of pollution in the water.
Jellyfish have been increasing for the past 10 years. That means that the
pollution hasn’t harmed the jellyfish yet. We don’t know yet if How long have jellyfish been on this earth? Jellyfish have been on this earth for a very long time. They have been on for 450,000,000 years. That’s longer that dinosaurs! What happens when jellyfish get washed up to shore? When jellyfish get washed up to shore they can’t get back in the water. If you spot one laying on the beach remember where you saw it. Go back the next day. Then you will find that the jellyfish has melted. When jellyfish melt, all there will be is some of its skin surrounding the jellyfish. The inside will have evaporated. Conclusion When you finish researching jellyfish you go back to the same spot you saw a jellyfish. Now you don’t see a jellyfish, you see a…(FIND OUT ON MY NEXT REPORT!)
