The lion is a large predatory cat with a powerful body and strong paws. Males are distinguished by a large mane on the head and neck, and all lions live in groups called prides.
The lion differs from other big cats by living and hunting in prides. As the main predator of the savanna, it helps maintain balance by controlling the population of herbivores.
