For the first time in New Zealand waters an extremely rare grouping of Shepherd's Beaked¹ Whales has been spotted² from a University of Otago research vessel³ off the coast of the city of Dunedin in the South Island. Dr Will Rayment, from Otago's Department of Marine⁴ Science, last week led a survey expedition of the submarine canyons⁵ off the Otago coast aboard the vessel Polaris II, and revealed the two separate sightings of the whale today. The survey team comprised researchers from Otago University, Yellow-eyed Penguin⁷ Trust, Otago Museum, Parker Conservation and the Ornithological⁸ Society of NZ.

 

The Shepherd's Beaked Whale, Tasmacetus shepherdii, is one of the least known cetaceans in the world, and was previously⁹ known from only nine confirmed sightings in the world of live members of the species, and 55 strandings of dead whales.

 

"There have previously been no confirmed sightings in New Zealand waters, although New Zealand is the world's stranding¹⁰ hotspot for the species," he says.

 

"On Tuesday (28 June) the team saw a group of five beaked whales in the Taiaroa Canyon⁶, about 30 km east of Taiaroa Head. They were confident they had just sighted the unusual Shepherd's beaked whale, mostly because one of the team, Dr Trudi Webster, had recently attended a stranding on the Chatham Islands.

 

"Amazingly, the very next day, the team made another sighting of the rare species, this time a group of three in the Saunders Canyon, also off the coast of Dunedin. Both sightings were later confirmed as Shepherd's Beaked Whales by Anton van Helden, NZ's beaked whale expert."

 

"The team saw a range of seabird and marine mammal species, but the highlight was undoubtedly¹¹ the two sightings of this rare and elusive¹² whale."
