Why do Amur leopards have rough tongues?

Amur leopards have rough tongues due to the presence of papillae, which are small, hook-like structures that help them effectively groom their fur and consume their prey. These barbed structures enable the leopards to scrape meat off bones and remove fur or debris while grooming. This adaptation is crucial for their survival, as it aids in maintaining their health and enhancing their hunting efficiency. Additionally, the rough texture of their tongues helps in the consumption of various prey, contributing to their role as apex predators in their habitat.
