A leucistic cougar walks through southeastern Brazil's Serra dos Órgãos National Park on July 5, 2013.
Move over, black panther—there’s a white cougar in the limelight. Photographs recently resurfaced of a ghostly young male striding through Serra dos Órgãos National Park in southeastern Brazil’s Atlantic Forest. Taken in 2013, the photographs were the first confirmed case of a wild cougar with leucism, a genetic mutation that turns most of its body white.
