This nocturnal creature uses its elongated middle finger to tap on trees, detecting insects beneath the bark.

Indian pangolins are solitary, nocturnal creatures covered in tough, overlapping scales. Found in forests and grasslands, they use their powerful claws to dig for ants and termites, their primary food source.

While harmless to humans, their unique abilities and appearance make them a standout among nocturnal aquatic predators.
11. Striped Hyenas: The Mysterious Scavengers
