<span>After being introduced into the
Hawaiian Islands, the cane toads greatly affect local ecosystem. In the new area, they
have a few natural predators and are able to spread. If they spread beyond
the area they are introduced, they become invasive species which can

This could lead to the extinction of some native species.</span>
