Enigmatic
orcas 'could be the largest undescribed animal left on the planet',
say marine researchers
A killer
whale that could be a new species is to be studied by scientists for the first
time after it was seen off the coast of southern Chile.
A team of
international researchers have collected genetic samples from a group of orcas
roaming the sub-Antarctic waters off the tip of South America.
For
decades, fishermen and tourists had returned with tales and even photos
of killer
whales in the region that look distinctly different from
others. But the enigmatic marine mammals had eluded scientists until now.
The team
encountered the killer whales – known only as “Type D” – while anchored
off Cape Horn for
a week waiting for storms to pass in January.
Scientists
collected three biopsy samples from the pod, and biologists from the US
National Oceanic and Atmospheric Administration (NOAA) are now conducting
laboratory tests that will establish if the orcas are a new species.
