Albino, or all white, deer completely lack the pigment melanin. Melanistic, or black, deer have more melanin than usual. All three conditions are rare, affecting fewer than one in 100 deer.
A melanistic Royal Bengal Tiger (RBT), one of the rarest subspecies, was killed by poachers in Similipal Tiger Reserve, a habitat that is home to an estimated 20 of these unique black-striped cats.
