|“||And lions are fierce. It's kinda common knowledge, really.||”|
In the Real World
Physically, lions are a tawny golden color and are the only cats whose sexes can be told apart at a distance. Males bare thick, shaggy manes of either blond, black, red, or brown, while lionesses are barren around the neck. Both sexes have a tail tuft, always black in color, though cubs are born without this tuft. Lion eyes are most commonly amber, but brown, green, and blue eyed lions have been observed. A male lion is roughly twice the weight of a female, at 420 pounds, while lionesses only weigh 290. The age of a lion can be told by examining how dark its nose is. Lion cubs startup with a nearly pink coloured nose. An older lion has a light brown and the very old are spotted by their dark brown noses. If you want to find a certain lion that you observed this trick will help out: By counting and looking closely at the lion's whiskers you can recognise each lion individually. Each lion has a unique pattern and amount of whiskers that stays with it as long as the animal lives.
A lioness can have when pregnant a litter of one to four lion cubs. Rarely, a pair of lions will give birth to a white lion. A lion cub is born with little, brown spots on its legs. As the cub grows older those start to vanish and disappear completely when having reached adulthood. But there has also been seen some lions that maintained their brown spots after they were full grown. 
In The Lion Guard
As far as looks go, lions in The Lion Guard franchise are far more diverse. They range from gold, cream, tawny, tan, brown, and reddish-brown. Their eyes have a wide color range as well, including brown, red, orange, green, and blue. For Pride Lander lions, the males are usually portrayed as being bigger and more muscular than the lionesses and are also identifiable by their manes. They tend to have brightly-colored fur, often yellow or orange shades, with goldish undertones. Their manes are most often red or orange. However, the paintings of Scar's Lion Guard showed that they all had dark fur tones and brown manes, and another painting in The Lair of the Lion Guard depicted a Guard with black manes. The lionesses, meanwhile, are more slender, built for hunting and speed. They tend to have duller and/or paler colors than the males.
In the Real World
Lions live in different parts of Africa and Asia. They are the second largest big cat after the tiger. They spend around sixteen-twenty hours of their day sleeping and resting. A lion's roar can be heard from five miles away.
When lionesses come into heat, the male lion will indiscriminately mate with all of them to increase the chance of spreading his genes via offspring. Cubs may be born to different mothers or share a father if only one male is present. Cubs born in the same litter may also have different fathers, especially if the pride that they and their mother are a part of is dominated by more than one male. Even if the litter consists of only two cubs, there is still a chance that they may only be half-siblings, whether their mother mated with a rogue male in addition to the pride male or if the pride consists of two males and the mother mated with them both. Cubs practice their hunting skills by stalking each other. Like many cats, lions see well in the dark.
