Leopards are part of the species, Felidae, in the subspecies, Pantherinae. They are solitary hunters and have been known to hide and hunt for prey in very strange places such as, caves, rivers, and even trees!
Like all of the Pantherinae subspecies, leopards are apex predators; this means that they sit at the very top of the food chain.
The only real competition leopards have for food is other leopards.
Interestingly, leopards use their spots to communicate. They do this by moving their ears and tails to change the way their spots look to other leopards to indicate whether they are hunting or ready to reproduce.
