The nutria, also known as a coypu, is a large, water-living rodent that is an invasive

species in Texas. The nutria lives in coastal marsh regions and feeds on small trees and

other plant life. It was originally brought to Texas and bred for its fur. However, with the

decrease in the fur industry, the populations have increased significantly. As a result,

thousands of acres of marshlands along the Gulf coast have been destroyed. Besides destroying the marshland habitat, how does the nutria harm other animals that live in the Texas coastal marshland regions?

• They eat other animals in the marsh region.

• They chase other animals out of the marsh

  region.

• They cause the other animals in the marsh

  region to reproduce more.

• They compete for food with other animals in

  the marsh region.
