Lions and mountain lions belong to entirely different genera and differ dramatically in size, appearance, social behavior, and range, despite both being big cats.
Taxonomy and classification
- The lion (Panthera leo) belongs to the genus Panthera, which also includes tigers, jaguars, and leopards — cats capable of roaring due to a specialized larynx and hyoid structure.
- The mountain lion (Puma concolor), also called a cougar, puma, or catamount, belongs to the genus Puma. It's more closely related to smaller cats like the cheetah and domestic cat than to true lions. Mountain lions cannot roar; instead they make sounds like screams, hisses, growls, and purrs.
Physical differences
- Lions are much larger and more heavily built, with males typically weighing 330–550 pounds and sporting a distinctive thick mane around the head and neck — a feature unique to male lions among big cats.
- Mountain lions are smaller and leaner, with males usually weighing 115–220 pounds. They have no mane, a small head relative to their body, and a notably long, thick tail that can be about a third of their total body length.
Coloring
- Lions have tawny, sandy, or golden-brown coats.
- Mountain lions have a more uniform tan, gray-brown, or reddish coat, often lighter on the belly.
Habitat and range
- Lions are native to sub-Saharan Africa, with a small, critically endangered population in India's Gir Forest. They favor grasslands, savannas, and open woodlands.
- Mountain lions have the largest range of any wild land mammal in the Western Hemisphere, found from Canada through the western United States down to the southern Andes in South America. They adapt to mountains, forests, deserts, and swamps.
Social behavior
- Lions are unusually social for cats, living in prides of related females, their cubs, and a small number of males.
- Mountain lions are solitary and territorial, coming together only briefly to mate, with females raising cubs alone.
