World's rarest whale seen for first time in New Zealand

Rarest whale: Two spade-toothed beaked whales, a mother and calf, were stranded on a beach in New Zealand. This is the first time this species of whale has ever been seen as a complete specimen.

The world's rarest whale has been spotted for the first time, in New Zealand, where two of the whales stranded themselves.

The two spade-toothed beaked whales, a mother and calf, stranded and died on Opape Beach on the North Island of New Zealand, in December 2010. The mother was 17 feet (5.3 meters) long and the calf was 11 feet (3.5 m) long.

A report describing the whales and the analysis of their DNA appears in the Nov. 6 issue of the journal Current Biology.

"Up until now, all we have known about the spade-toothed beaked whale was from three partial skulls collected from New Zealand and Chile over a 140-year period. It is remarkable that we know almost nothing about such a large mammal," Rochelle Constantine, a marine biologist at the University of Auckland in New Zealand, said in a statement. "This is the first time this species has ever been seen as a complete specimen, and we were lucky enough to find two of them."

At first, the animals were thought to be much more common Gray's beaked whales. Their identity came to light following routine DNA analysis, which was done as part of a 20-year program to collect data on beaked whale species in New Zealand waters. New Zealand is a known hotspot for whale stranding, and it has the highest rates and greatest diversities of stranded whale species in the world, the researchers report.

The New Zealand Department of Conservation photographed the animals and collected tissue samples.

"When these specimens came to our lab, we extracted the DNA as we usually do for samples like these, and we were very surprised to find that they were spade-toothed beaked whales," Constantine said. "We ran the samples a few times to make sure before we told everyone."

The researchers said they have no idea why the whales have remained so elusive.

"It may be that they are simply an offshore species that lives and dies in the deep ocean waters and only rarely wash[es] ashore," Constantine said.

Because the spade-toothed beaked whale has never been seen alive, nothing is known about its behavior.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
