The Jolly Jellyfish
Cate Sulzer
Introduction
Did you know that there are hundreds of different organisms that live in the water near Australia? Jellyfish are enthralling creatures. They have a thrilling way of moving around the ocean, a captivating body structure and appearance and also their habitat is in the bright blue oceans all over the world.
Movement Jellyfish have an easy way of moving around in the ocean. These creatures are dependent on the currents, tides and winds in the water. Jellyfish have little control over their side to side movement, but have more control over their up and down movement. During the daytime, jellyfish move down to the bottom of the ocean because they are sensitive to light. Jellyfish need water to survive. | Body Structure and Appearance Jellyfish can appear to be multicolored or show some magnificent colors such as white, pink, yellow, orange, red, blue or green. Some jellyfish can also be nearly transparent or see through. These creatures lack a skeletal structure and can appear as a jelly-like, shapeless blob. Jellyfish are made up of a gelatinous substance, which is 95% water. This creature is also made up of 3 layers: the outer epidermis, inner gastrodermis and the middle mesoglea. There are fringe-like protrusions that are attached to the outside of its bell-shaped body which are called tentacles. These tentacles are filled with toxins and possess hair-like structures, these can sense the presence of prey. | Habitat These amazing creatures are found in oceans across the planet from the coldest freezing waters of the Arctic Oceans, to the warm waters of the tropical oceans. Jellyfish survive in different marine water conditions, cold and warm water and shallow coastlines or deep sea water. They are found in the bright blue oceans all across the United States and in Europe. |

Closing
In conclusion, I learned so much about jellyfish that I didn’t know before. The body structure and appearance of jellyfish are interesting to learn about. I learned about the unique way that jellyfish move through the ocean. Their habitat is in the ocean and is fascinating because they live all over the world. I really liked learning about the jellyfish.

Go Fish!
I really enjoyed this activity because it was fun to do and I was able to pick out my own fish for my fish tank. I bought 10 fish for my tank, I picked out different fish that were colorful and kind of small so that they all fit in the tank. I chose two Yellowtail Blue Damsel, three Red Female Veiltail Betta, two Strawberry Dottybacks, one Male Halfmoon Betta, one Green Mandarin Goby and a Dwarf Zebra Lionfish. I spent $80.10 on the ten fish that I bought for my fish tank. I will need 20 gallons of water for my tank for my fish to survive. I spent $228.37 on my tank, the decorations and the fish. I spent less than the money I had budgeted for, I was given $250 and still had money left over. This was one of my favorite parts of the project, I think the students next year should do this too, they will like it a lot.
