Wellington, New Zealand:
New Zealand scientists on Monday started dissecting a whale thought of the rarest on this planet, a species so elusive that solely seven specimens have ever been documented.
The lifeless spade-toothed whale washed ashore on New Zealand’s South Island earlier this yr, providing an opportunity to review a deep-sea mammal that has by no means been seen alive.
Measuring 5 metres (16.4 toes) lengthy, the whale was winched off the seashore in July and has sat in a particular freezer since.
Whale knowledgeable Anton van Helden stated it was the primary time scientists had been in a position to dissect a whole spade-toothed specimen, which belongs to the household of beaked whales.
“It is a exceptional and globally vital alternative,” he stated.
The week-long dissection will assist to fill in gaps concerning the whale’s behaviour, its food regimen, and even its primary anatomy.
“Beaked whales are essentially the most enigmatic group of enormous mammals on the planet,” stated Van Helden.
“They’re deep divers which might be not often seen at sea, which presents actual challenges for researching these marine animals.
“This one is the rarest of the uncommon — solely the seventh specimen recognized from anyplace on this planet, and the primary alternative we have now needed to undertake a dissection like this.”
New Zealand’s conservation division stated the spade-toothed whale was the “rarest whale on this planet”.
The species was first described in 1874 from only a decrease jaw and two tooth collected from the Chatham Islands off the east coast of New Zealand.
That pattern, together with skeletal stays of two different specimens present in New Zealand and Chile, enabled scientists to substantiate a brand new species.
As a result of so few specimens have been discovered and there have been no stay sightings, the spade-toothed whale is classed as “knowledge poor” underneath the New Zealand Risk Classification System.
