Harrison WorldLAB Symposium

 
Topic: Jellyfish
Group Members: Autumn, Darnell, and Krista
 
Question : What are jellyfish, and how is there life like in the ocean?
Overview of the three required learning activities:
1. web page
2. survery
3. talk to an expert over E-mail
 
Findings (list): Jellyfishes are very unique in many ways.
1. We learned that there are over 2000 species of jellyfish in the world.
2. Jellyfish are invertebrates and they are relatives of sea anemones and corals.
3. Jellyfish are more than 95% water, without hearts, brains, bones, or eyes.
4. There is one jellyfish that can live in freshwater and it is called the Craspedacusta sowerbii.
5. Japan and other parts of Asis eat jellyfish as part of thier daily diet.
6. The main predators of jellyfish are sea turtles and other jellyfish.
7. The largest jellyfish grows to over 200 feet in length and has a bell diameter of over 8 feet.
8. History shows that jellyfish existed over 700 million or more years ago.
9. Most jellyfish relay on the oceans current for movement.
10. The tentacles on a Jellyfish carry stinging cells that are among the most complicated found anywhere in the whole animal kingdom.
 
Conclusion: how was question answered: Jellyfish are creatures who mostly survive on the oceans current for movement. Many of the jellyfish are almost transparent and are made out of 95% water, made of 4% salt, and 1-2% protein.
 
Questions raised for further study:
1. What is the life cycle and the life expectatcy of a jellyfish?
2. Where is the largest jellyfish currently in captivity?
3. What is the effect of a jellyfish sting?
