TED-Ed: How do animals see in the dark? - Anna Stockl

The video explores how nocturnal animals have adapted their vision to see in low-light conditions. It explains the role of photoreceptors in detecting light and how different animals have evolved unique adaptations. Tarsiers have large eyes to gather more light, cats have a reflective layer to enhance photon detection, and toads have slow photoreceptors to collect more photons over time. Hawk moths group photoreceptors to see in color at night. These adaptations allow nocturnal animals to navigate and thrive in the dark.

What adaptations do nocturnal animals have that allow them to see in low light conditions?

How do the eyes of tarsiers compare to those of humans in terms of size and function?

Explain the role of the tapetum lucidum in the vision of cats.

What is the trade-off that hawk moths make in their visual perception?

Discuss how toads adapt their vision to their hunting style.
