Lionfish are a predatory reef fish that feeds on native populations. They are currently found in Southeastern US coastal waters from Florida to North Carolina, and appeared around 1985 from an unknown cause. These fish have venomous spines for defending themselves from their natural predators, which are absent from the Atlantic Ocean area that they have been found in. Therefore, divers and fishermen are allowed to harvest and dispose of them, but not to feed them to another animal as that would be inhumane. How would lionfish be classified?
A. climax species
B. invasive species
C. pioneer species
D. succession species
