Invasive animals are introduced multicellular organisms of the kingdom Animalia. Examples of invasive animals include mammals, birds, reptiles, and insects.

What is an Invasive Species? An invasive animal has the ability to thrive and spread aggressively outside its native range. A naturally aggressive animal may be especially invasive when it is introduced to a new habitat.

Invasive aquatic animal species are included in our Aquatic Species - Aquatic Invasive Animals section.
