Whale species is new to science
BBC: A previously unidentified species of whale has been recorded by researchers.
The creature is a close cousin of the blue whale and has been given the formal scientific name Balaenoptera omurai, reports the journal Nature.
Its Japanese discoverers say the 12-metre-long animal's DNA and anatomical features mark it apart from other whales that use combs to trap food.
Commentators believe the new finding may complicate the debate over whether commercial whaling should be resumed.
It was likely to delay any return to the regular harpooning of certain whale species, they told the BBC.
