AQUATIC INVASIVE SPECIES

WHAT MAKES A SPECIES INVASIVE?

A competitive edge.

Invasive species are generalists. They can eat a wide range of foods and survive in many conditions.

Catch me... if you can?

With few natural predators invasive species can continue to breed, eat, and out-compete native species.

Baby BOOM!

Whether hundreds of seeds or millions of eggs, invasives have a reproductive advantage that allows more offspring to survive and continue the cycle.
