A nocturnal, forest-dwelling primate with orb-like eyes and short limbs was photographed in central Sri Lanka late last year after being feared extinct, researchers said Monday. A Horton Plains slender loris was caught on camera after lengthy surveys of the forest by researchers from the Zoological Society of London, the University of Colombo and the Open University of Sri Lanka. Team leader Saman Gamage said the mammal was not sighted for more than 60 years until in 2002 a researcher reported spotting its eyes during a search - inspiring the effort to view it fully and photograph it. The primate's population is thought to have begun dwindling in the mountain forest habitat after British colonial rulers from the 19th century cleared large tracts of forest for coffee and tea plantations, Gamage said.
