* Location: A valley in the Amazon rainforest will have very different life than a valley in the Himalayas.
* Climate: Valleys can be hot and dry, temperate, or cold and snowy. This greatly influences the plants and animals that can survive there.
* Elevation: Valleys at high altitudes will have different plant and animal life than those at sea level.
* Soil Type: The type of soil in a valley affects the types of plants that can grow there, which in turn impacts the animals that can live there.
General examples of animals and plants found in valleys:
* Mammals: Deer, elk, rabbits, squirrels, foxes, bears (depending on location)
* Birds: Hawks, owls, songbirds, woodpeckers, eagles (depending on location)

To get a more specific answer, you need to tell me more about the valley you're interested in! For example:
* Where is the valley located?
* What is the climate like there?
* What is the elevation of the valley?
Once I have this information, I can give you a more accurate and helpful answer.
