Why do we classify lionfish populations near the eastern united states as an invasive species? what suggests that these new populations are not an expansion of the lionfish’s natural range?

The correct answer is that lionfish are native to tropical which is found in pacific. In pacific ocean you can not find warm water and for the population of lionfish will not expand in natural range.

The population which is found near the eastern united state is termed as invasive species because lionfish are known to be native tropical which are being found in pacific ocean.

Lionfish affects the commercial fishing industries and also the native fish population. Species which are non native can affect local fishing economies and native ecosystem.
