Water bears get there nickname from the way they walk which greatly resembles the way an actual bear does.

4. In order to survive in extreme situations and environments, water bears go into a dry state that is almost like hibernation. What is this state called?

Answer: Cryptobiosis

During a state of cryptobiosis, the water bear is actually capable of completely reversing its metabolism.
Gluconeogenesis is the process by which a hibernating animal gets energy.
A haemocoel is a type of body cavity.

5. Who was the first person to describe the water bear and is therefore called its discoverer?

Answer: Johann August Ephraim Goeze

Johann August Ephraim Goeze was the first person to describe the water bear and is therefore called its discoverer.
Lazzaro Spallanzani actually gave the water bear its name years after Goeze first described it.
Jean-Baptiste Lamarck was an evolutionist who had the right concept but the wrong ideas.
Ian Wilmut was actually one of the men who helped clone Dolly the sheep.

6. Which of the following best describes the water bear's current status in terms of how many there are in the world?

Answer: Low Risk

Water bears are about as low risk as you can get. There are an abundance of them all over the world!

7. Water bears can survive in environments of extreme pressure. Fill in the blank and complete the sentence with the best choice: Water bears can survive in an environment that has six times the amount of pressure than ___________________________________________.

Answer: the deepest ocean trench on Earth

Water bears have shown that they can survive in an environment that has 6,000 atmospheres of pressure. That's equivalent to about six times more than the deepest ocean trench on Earth!

8. Due to the fact that water bears can survive pretty much any situation you put them in, they are known as what type of extremophile?

Answer: Polyextremophile

A polyextremophile is an organism that has traits of many different kinds of extremophiles. Water bears can, among other things, survive temperatures of 303 degrees Fahrenheit and -460 degrees Fahrenheit, live for over 100 years without water, and survive ten days in outer space with no protection.
A cryophile is an organism that thrives at very low temperatures.
A xerophile is an organism that can live and reproduce in environments with little or no water.
A piezphile is an organism that thrives in high pressure.

9. What body systems does a water bear NOT have?

Answer: Circulatory/Respiratory Systems

Due to the small size of water bears, they have no need for any body systems that specialize in gas exchange. Therefore, they do not have a circulatory system or a respiratory system.

10. Where is the most convenient place for the average observer to find a water bear?

Answer: On Lichens (a Type of Fungi) and Mosses

While the water bear has been found in all of the above locations, by far the most convenient is on lichens and mosses. That means you can go out back and find a water bear in your own yard!
