Hang in there, little guy: Scientists in Sri Lanka recently photographed the Horton Plains Loris—an animal so rare that they thought it was extinct for much of the past 60 years. The small tree-dwelling primate has only been seen four times since 1937 and was last spotted in 2002, when scientists identified the reflection of a light shown in its distinctive round eyes. The picture shows a male loris clutching a tree branch, and it didn’t come easily: Researchers carried out more than 1,000 nighttime surveys before snapping the photo.
