Quiz Answer Key and Fun Facts

1. What is interesting about the digestive system of a jellyfish?

Answer: It is very simple, with only one opening

A jellyfish eats food through its mouth, which can be found on the bottom of its body, also known as the bell. They excrete through the same opening.

2. What is a simple analogy used to describe the way a Jellyfish 'pounces' through the water?

Answer: 'a simple form of jet propulsion'

To move forward, the jellyfish makes a jet of water that moves it quickly forwards. The jellyfish also drifts on water currents to move; though this could be taken as the answer 'smooth, slow, hardly any movement', this does not describe how it pounces.

3. Jellyfish lack brains, blood and hearts.

Answer: True

They get on just fine without these, vital to most other living creatures, though their senses are very primitive.

4. How many layers does a jellyfish's body consist of?

Answer: Three layers

The outer layer is the epidermis, then they have the inner layer and of course the middle layer which has in it a thick substance known as the mesoglea.
All play an extremely important role for the jellyfish.

5. How many known species are there of 'true' jellyfish?

Answer: about 200

The 'true' jellyfish species include: moon jellies, Mediterranean jellyfish, sea nettles (known for stinging very painfully), lion's mane jellyfish (which can be HUGE), blue jellies, and many other lesser known species.

6. What is interesting about the size of a jellyfish?

Answer: Jellyfish range from as big as a human to as small as a pinhead

The lion's mane jelly has been reported to be the biggest recorded jellyfish. The Irukandji jellyfish is reported to be the smallest.

7. What is the average life expectancy for a Lion's Mane jellyfish?

Answer: Less than one year

Jellyfish live less than one year on average, however the smallest species of the jellyfish may live only a few days. They have just enough time to mate, and then they die.

8. What can people do with jellyfish?

Answer: Eat them

Many people are known to eat jellyfish, and they have been said to be 'delicious'. In various cultures fried jellyfish is popular, and in many restaurants around the world they are treated as a delicacy. Jellyfish are not usually eaten raw.

9. The word 'jellyfish' is a common term used to describe animals that are what?

Answer: Gelatinous or made up of 'jelly-like' material

The word 'jellyfish' is a common term used to describe animals that are made up of 'jelly-like' material.

The dictionary definition for a jellyfish is a 'jelly-like sea creature'. This reflects highly on the fact that the jellyfish lives in the water. Jellyfish die on land. If one was to go to Australia, for example, during the summer seasons washed up jellyfish are very commonly found along the sand.

10. How is the diet of a jellyfish classified?

Answer: Carnivorous

Jellyfish feed on small fish, other jellyfish, plankton and fish roe.
