What animal does not migrate?

It's impossible to say definitively which animal never migrates. Migration patterns are complex and can vary widely even within a species.

However, some animals that are generally considered non-migratory include:

* Many mammals: Domesticated animals, squirrels, raccoons, and many other mammals living in stable environments tend not to migrate.

* Some birds: Birds that live in tropical rainforests with abundant food year-round might not migrate.

* Reptiles and amphibians: Many reptiles and amphibians have relatively small ranges and don't migrate long distances.

Remember:

* Climate change is altering migration patterns for many species.

* Human activities can also disrupt migration routes.

It's always best to consider the specific species and its environment when assessing migration patterns.
