Sure, let's take a look at some of the majestic big cat species found around the globe:

1. **Lion** (*Panthera leo*)
   - **Appearance:** Adult male lions are unique among big cats for their thick mane of brown or black hair encircling their heads. They have a tawny coat, and their tails end with a hairy tuft. Female lions, or lionesses, are smaller and lack the distinctive mane.
   - **Trivia:** Lions are the most social of all big cats and live together in groups or "prides." The females in the pride tend to do most of the hunting.

2. **Tiger** (*Panthera tigris*)
   - **Appearance:** Tigers are known for their beautiful striped coat, which varies from orange to tawny, densely striped with black. They have a white chest and belly and a thick ruff of fur around their necks.
   - **Trivia:** The Siberian Tiger is the largest wild cat in the world. Each tiger has a unique set of stripes, much like a human's fingerprints.

3. **Leopard** (*Panthera pardus*)
   - **Appearance:** Leopards have a large, muscular body with a long body and tail. Their coat is a tawny color with black rosettes.
   - **Trivia:** Leopards are incredibly strong and are known for their ability to climb trees. They often haul their kills into the branches to eat in peace.

4. **Jaguar** (*Panthera onca*)
   - **Appearance:** Jaguars are often confused with leopards due to their similar coats. However, they are typically larger and more robust. Their rosettes are larger, too, often with spots in the center.
   - **Trivia:** Jaguars have the strongest bite force of all big cats relative to their size. They often kill their prey with a single bite to the skull.

5. **Cheetah** (*Acinonyx jubatus*)
   - **Appearance:** Cheetahs are slender and lightweight compared to other big cats. They have a small head, high-set eyes, and a coat that is tawny to pale with small, round black spots.
   - **Trivia:** Cheetahs are the fastest land animals, capable of speeds up to 60-70 miles per hour in short bursts covering distances up to 1,500 feet.

6. **Snow Leopard** (*Panthera uncia*)
   - **Appearance:** Snow leopards have long, thick fur that is smoky gray with black rosettes. Their tails are thick and long, which they use for balance and as a blanket for warmth.
   - **Trivia:** These cats are perfectly adapted to cold, mountainous environments, with thick fur and wide, fur-covered feet that act as natural snowshoes.

7. **Cougar** (*Puma concolor*), also known as Mountain Lion or Puma
   - **Appearance:** Cougars have a slender and agile body covered by a coat that varies from tawny to silver-gray or reddish color. They do not have rosettes or stripes, unlike many other big cats.
   - **Trivia:** Cougars have the largest range of any wild terrestrial mammal in the Western Hemisphere, spanning from Yukon in Canada to the Southern Andes of South America.

Here's a quick comparison table of their average sizes:
