How can some animals see in the dark?

What is your name?

Which of the following models best describes the path of the light?

• tarsier’s eye sends out light → light reflects off branch → light goes to Sun
• light reflects off branch → light goes into tarsier’s eye → light goes to Sun
• light travels from Sun → light reflects off branch → light goes into tarsier’s eye
• light travels from Sun → light goes into tarsier’s eye → light reflects off branch

2. Chose the drawing that you think is of the tarsier at night.

• Drawing A
• Drawing B

3. Tarsiers are most active at night. That’s when they move around and hunt for insects to eat. Look back at the drawing you chose in question 2. Explain two things: why the tarsier’s eyes look the way that they do, and how that might help the tarsier find insects to eat at night.

4. Tarsiers climb around at night, looking and listening for insects to eat. To do those things, they need hands, feet, eyes, and ears. Explain how those four body parts work together as a system to help the tarsier climb and find food when it is completely dark out.
