Why is the South American squirrel monkey a invasive species?

The South American squirrel monkey (Saimiri sciureus) is not considered an invasive species.

Here's why:

* Native Range: Squirrel monkeys are native to South America, specifically in the Amazon rainforest and surrounding areas. They are not introduced outside of their natural range.

* No Evidence of Invasion: There is no documented evidence of squirrel monkeys causing ecological harm or outcompeting native species in areas outside their native range.

* Captive Breeding: Squirrel monkeys are sometimes kept in captivity, but they are not typically released into the wild outside of their native range.

Confusion with other species:

There might be confusion with other species, like the common marmoset (Callithrix jacchus). This species *is* considered invasive in some parts of the world (like Florida) because it was introduced outside its natural range and has established populations that can outcompete native species.

It's important to be specific when talking about invasive species. Always check the scientific name of the species to avoid confusion.
