Bengal tigers, scientifically known as Panthera tigris tigris, are specifically found in the Delta area. Here is an explanation of why this is the correct answer:

Bengal Tigers
- Bengal tigers are one of the six tiger subspecies and are native to the Indian subcontinent.
- They are known for their distinct orange coat with black stripes, which provides excellent camouflage in their habitat.

Distribution
- Bengal tigers are primarily found in India, with the largest population residing in the Sundarbans mangrove forest in the Ganges Delta.
- The Sundarbans is a vast delta formed by the confluence of the Ganges, Brahmaputra, and Meghna rivers, and it spans across India and Bangladesh.
- This delta region is recognized as a UNESCO World Heritage site and is home to the largest population of Bengal tigers.

Habitat
- The Delta area provides a unique habitat for Bengal tigers due to its combination of mangrove forests, freshwater swamps, and tidal mudflats.
- The tigers are adapted to this specific environment, where they can swim, wade through water, and move through the dense vegetation.
- The mangroves serve as an ideal hunting ground for the tigers, as they provide cover and attract prey such as deer, wild boar, and various types of birds.

Threats and Conservation
- Despite being found in a specific region, Bengal tigers are classified as an endangered species due to various threats.
- Habitat loss, poaching for their body parts, and human-wildlife conflict are some of the major challenges faced by these tigers.
- Conservation efforts, including protected areas, anti-poaching measures, and community involvement, are crucial for the survival of Bengal tigers.

In conclusion, Bengal tigers are specifically found in the Delta area, particularly in the Sundarbans mangrove forest of the Ganges Delta. This region provides the perfect habitat for these majestic creatures, allowing them to thrive and maintain their population.
