The Department of Conservation is appealing for information to help track down the person responsible for decapitating a seal body.
In a statement, DoC said the dead leopard seal was decapitated over the weekend at Monkey Island in Southland.
DoC was first alerted to the dead leopard seal last week and, after communicating with local Oraka Aparima rūnaka, it was decided to allow the animal to naturally decompose.
However, DoC said the leopard seal's body was decapitated over the weekend, to the horror of both groups.
DoC senior biodiversity ranger Ros Cole said the act was both incredibly disrespectful, and illegal under the Marine Mammals Protection Act.
