The killing of a collared lion involved in a research project in Zimbabwe by a trophy hunter has been condemned by wildlife groups

The killing of Cecil ignited fury and protests against the hunter behind it—Minnesota dentist Walter Palmer—and brought attention to the issue of big game trophy hunting. Palmer reportedly paid $50,000 to his guides to help give him the opportunity to kill Cecil, which he did using a bow and arrow.

A trophy hunter who legally killed a lion in Zimbabwe that was part of a study has drawn criticism from wildlife advocates.
