Brief Explanations:

Cane toads are not native to the Hawaiian Islands. They were introduced (not naturally occurring), and invasive species are non - native species that cause harm. Uncontrolled species is a very broad and not a standard ecological term for this context. Endangered species are at risk of extinction, which is not the case for cane toads in Hawaii. Since they are non - native and cause ecological disruption (e.g., by preying on native species and having few natural predators in the new environment), they fit the invasive species category.

Answer:

invasive species
