The Odisha Forest Department has arrested 4 poachers belonging to the Lodha tribe for the illegal hunting of a rare melanistic tiger in Similipal Tiger Reserve (STR), Odisha.

What are the Key Facts Regarding Melanistic Tiger?
- Melanism and Melanistic Tiger: Melanism is a genetic condition where animals produce more melanin, leading to darker or black skin, fur, or feathers.
- Melanin is a natural substance that gives color to the skin, hair, and eyes.
- The Royal Bengal Tigers of STR have a unique genetic trait with higher melanin levels, resulting in a pattern of black and yellow stripes, making them pseudo-melanistic.
- The All Odisha Tiger Estimation (AOTE) 2023-24 report estimates that STR hosts 27 tigers, including 13 adult pseudo-melanistic tigers, a unique trait not found in any other wild habitat.
- Other Color Variations in Tigers:
- Orange with Black or Brown Stripes: This is the most common and well-known coloration, seen in tigers like the Royal Bengal Tiger.
- Each tiger has a unique stripe pattern that helps with camouflage in their natural habitat.
- White Tigers: White tigers are not a separate subspecies. Their white fur is due to a genetic mutation called leucism, which reduces pigmentation, resulting in pale-colored skin, fur, or scales.
- Golden Tigers: They are also not considered a distinct subspecies. Their golden coloration is caused by a recessive gene called "wideband," which reduces melanin production during hair growth.
- This variation has been observed in Kaziranga National Park.
- Orange with Black or Brown Stripes: This is the most common and well-known coloration, seen in tigers like the Royal Bengal Tiger.
