In my last two posts we discovered that the world's worst invading alien might be the lionfish, a native of the west Pacific and Indian Oceans that is now spreading out of control in the Atlantic, from South America to New England. The lionfish's venomous spines ward off all native predators, while its own appetite makes it a super-predator of juvenile native reef fishes.

The only countering hope is the baddest predator in the sea, whose appetite out-eats all others. Look in the mirror, my friend.
