Killer whales hunt dolphin

A dramatic video has emerged from New Zealand of a pod of killer whales hunting a dolphin.

The rare footage, which was captured by a group of fishermen last month, shows the killer whales relentlessly pursuing the dolphin before finally catching it and finishing it off.

"The first known hunt of a bottlenose dolphin by killer whales in New Zealand waters," the filmer wrote online.

"This nature laid out cold and bare," he added.
