  • Melanistic tigers/Black tigers are found exclusively in the Similipal Tiger Reserve in Odisha.
  • They are a rare colour variant of the Bengal tiger.
  • Unlike the typical orange coat with dark stripes, melanistic tigers have a dark black or nearly black coat with faint or almost invisible stripes.
  • This dark colouration is due to a genetic condition known as melanism, where there is an excessive development of dark pigmentation (melanin) in the skin and fur.
  • A single mutation in the gene Transmembrane Aminopeptidase Q (Taqpep) causes the black tigers to develop broadened stripes.
  • Odisha is setting up an exclusive Melanistic Tiger Safari near Similipal Tiger Reserve.
