From British daily The Morning Star:
‘Extinct’ primate caught on camera
Sunday 18 July 2010
One of the rarest primates in the world, which was so elusive that it was thought to have become extinct, has been caught on camera for the first time, the Zoological Society of London (ZSL) has said.
The Horton Plains slender loris had only been seen four times since 1937 and vanished between 1939 and 2002, leading scientists to believe the wide-eyed mammal had become extinct.
ZSL researchers, who spent more than 200 hours looking for signs of the nocturnal primate in the mountain forest of central Sri Lanka, said they were “thrilled” to have photographed it.
