Why is the black rhino called hook lipped?

The black rhino is called "hook-lipped" due to its distinctive upper lip, which is pointed and prehensile, resembling a hook. This unique adaptation allows them to grasp and manipulate branches, leaves, and shrubs more effectively while feeding. Unlike the white rhino, which has a broad, square lip suited for grazing, the black rhino's hook-shaped lip helps it thrive in bushy and wooded habitats.
