Angry dolphin bullies swimmers off New Zealand coast

An aggressive four-year-old bottlenose dolphin has been accused of bullying swimmers and waterskiers in New Zealand.

Rescue services had to be called after the animal's intimidating behaviour prevented six people from swimming back to shore in separate incidents in the past week. Moko, who weighs some 250kg and used to live off Mahia on New Zealand's east coast, was initially praised for his friendly nature.

But since making Gisborne his home in September he has trapped swimmers, overturned kayaks, tipped over waterskiers, and interfered with surf lifesaving training.



Marine Science expert Professor Mark Orams has compared Moko's personality change to humans going through puberty. "He's doing what we all do as teenagers," he said. "He's testing his boundaries, but he's testing them on humans - and humans are coming off second best."

However, he expressed sympathy for the animal. "Here you've got a very lonely bottlenose who loves human contact, but he's getting way too big and strong for it," he said.

The expert said he was worried the situation would get worse, with either Moko being hurt or causing major injuries.
