Lionfish of New Providence Island
Relatively recently a change took place in the Bahamas that has had a devastating impact on the local ecosystem. An invasive alien species has been introduced - the lionfish. The lionfish is a fearsome predator and it's taking over.
This highly venomous fish was first found in Atlantic waters towards the end of the last century. It is a coral reef dwelling species originally found in the warm waters of the Indo-Pacific. In the Bahamas this invasive species is hunting the young of the indigenous fish, and with no natural predators, the lionfish population is exploding. They have already spread as far north as Rhose Island and as far south as the Caribbean.
