20 Amazing Lion Facts

The Lion (Panthera leo) is the second largest cat in the world, after the tiger. The lion and tiger are closely related and they share a very similar body type. As its scientific name suggests, Lion is one of the five members of the Panthera genus.Notes 1 Here are 20 amazing lion facts.

  1. Despite dubbed as the “king of the forest”, lions very rarely enter closed forest, and they are totally absent in rainforest. They prefer grassy plains and savannahs, open woodlands with bushes and scrub bordering rivers.
  2. Asiatic lion (Panthera leo leo) only lives in Gujarat, India. There are around 650 wild individuals.
  3. The lion is an apex and keystone predator. An apex predator is a predator residing at the top of a food chain upon which no other creatures prey. And if keystone predator is removed from the ecosystem, the populations of the species which it prey upon explode uncontrollably, driving out most other species. Ecosystems that lose their apex predators and/or keystone species often witness detrimental impacts within all trophic levels and consequently become dysfunctional.
  4. On Mount Elgon, an extinct shield volcano on the border of Uganda and Kenya, Lions have been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya (which is around 4600-4700 meters or more than 15,000 feet).
  5. Most felids remain quite solitary the in nature. But lion is the exception. They are very social animals and usually live in groups called “pride”. The average pride consists of around fifteen lions, including several adult females, up to four males. But extremely large prides, consisting of up over 30 individuals, have been observed.
  6. Not all lions live in prides. There is also another group with a different social behavior: nomads. Nomad lions range widely and move about sporadically, either singularly or in pairs. Pairs are more frequent among related males who have been excluded from their birth pride. Lions sometimes switch lifestyles: nomads may become a pride member and vice versa.

  7. Asian lions divide themselves into two prides. Male Asiatic lions are solitary or associate with up to three males forming a loose pride. Females associate with up to 12 females forming a stronger pride together with their cubs. Female and male lions usually associate only for a few days during mating season. They rarely travel and feed together, too.
  8. They sleep or rest around 16-20 hours a day. Male lions sleep more: they spend 18 to 20 hours a day snoozing, while females get 15 to 18 hours of sleep. Why do lions sleep so much? Because, like all cats, they have the physiology of a predator, and hunting prey takes an amazing amount of energy. All cats, including big cats, sleep a lot to reserve energy for running, pouncing, fighting and stalking. Lions, like all big cats, tend to be nocturnal, doing most of their hunting after dusk when it’s cooler, so most of their sleep is accumulated during the day. It’s also good for avoiding hot African sun.
  9. Male lions typically weigh between 150-250 kg (331-551 lb). Typical weight range for females is 120 to 182 kg (265 to 401 lb). Male African lions are 140 to 200 cm (4.5 to 6.5 feet) long from head to rump. Females range between 140 to 175 cm (4.5 feet to 5 ft 9 in) in body length. According to the World Wildlife Federation (WWF), Asiatic lions tend to be much bigger, 200 to 280 cm (6.56 to 9.18 feet) long (males).
  10. Lions live for about 10-16 years in the wild. Male lions tend to live shorter, because they sometimes engage into deadly fights with rival males. Captive lions, both males and females can live more than 20 years.
  11. Lions usually do not hunt people. But exceptions might occur. Some lions, mostly males, seem to seek out human prey. One well-documented example was Mfuwe man-eater, an enormous male lion that terrorized the small town of Mfuwe and the surrounds in the Luangwa River Valley of eastern Zambia. Another famous example was Tsavo maneaters. They were a pair of man-eating maneless male East African lions from the Tsavo region of Kenya, which responsible for the deaths of a number of construction workers on the Kenya-Uganda Railway from March through December 1898. The number of victims were probably 28 or 31. The Tsavo maneaters were killed by the project leader Lieutenant-Colonel John Henry Patterson. Why these lions started praying on humans, it is still controversial, but according to a National Geographic article, one of the Tsavo lions suffered from a broken canin. So he was seeking more easily subdued prey, maybe. The second Tsavo lion’s dental injuries weren’t too serious,so the animal likely learned to attack people from the other lion. This canin issue brings us to the next lion fact:

    Lion facts: Man Eater Lion of Mfuwe
    Man Eater Lion of Mfuwe, body on display at Chicago’s Field Museum. He was a huge lion, more than 3 meters (ten feet) from snout to tail. Like Tsavo Man-Eaters, he was totally maneless. Why there’s a white bag near him? Because, in 1991, after killing at least six people in a village, strutted through the center of the village. He was reportedly carrying a white laundry bag that had belonged to one of his victims. Mfuve man-eater was killed by a California man on safari.
    Like one of the Tsavo Man-Eaters, his health was not in perfect condition: he had fractured its right mandibular ramus. This may has been decisive factor influencing its consumption of humans.
  12. Lions rely heavily on their teeth to grab prey, suffocating the animal or collapsing its trachea. Because of this constant use, about 40 percent of African lions have dental injuries, according to a 2003 study.
  13. Lions are the only big cats with manes. The mane of the male lions usually considered a protective element during fights. In 1871, Charles Darwin suggested that the mane provides protection in intraspecific fights. But it also has an important role in sexual selection. If a male has a big, gorgeous and well-kept mane, this sends a signal to the females that this particular male is in a very good health condition, thus can be a good candidate to mate. The rule of thumb is the darker and fuller the mane, the healthier the lion. In the Serengeti National Park, female lions favour males as mates with dense, dark manes. During agonistic confrontations with other lions, the mane also makes the lion appear larger. According to a 2005 study, although the mane may have conferred protection during the early evolution of the trait, the protection appears to be secondary to the strong sexually selected advantages of the mane as a condition-dependent ornament. Another study, published in 2009, concludes “male manes may indeed mitigate the outcomes of intraspecific male attack”. This study also makes analogy between a lion’s mane and a man’s beard (and hair): “Humans also have unusual structural protections for the head, face and neck, areas that are especially accessible during intraspecies attack, and highly vulnerable to damage. One of these, the beard, consists of coarse hairs that grow indefinitely, but only for males, and only during and following puberty; suggesting that it, like the lion’s mane, may serve as protection in intraspecies male fights.”

    Male Lion
    The mane of a male lion has multiple purpose. The mane of male lions starts growing when they are about one year old. Mane color varies, and darkens with age.
  14. Lions are not very fast animals, while some of their prey are really fast. For example, a wildebeest can achieve a top speed of 80 kph. Lions are also not particularly known for their stamina – for instance, a lioness’ heart makes up only 0.57% of her body weight (a male’s is about 0.45% of his body weight), whereas a hyena’s heart is close to 1% of its body weight. Thus, they only run fast in short bursts, and need to be close to their prey before starting the attack. They take advantage of factors that reduce visibility; many kills take place near some form of cover or at night.
  15. Surprisingly, lions do not take into account wind direction when hunting. This is probably one of the reason of their relatively low hunting success rate.
  16. Lionesses are are polyestrous, meaning that they can go into heat several times per year. They give birth to 2-3 cubs at a time. Like house cats, lion cubs themselves are born blind and their eyes do not open until roughly a week after birth. Usually, the mother does not integrate herself and her cubs back into the pride until the cubs are six to eight weeks old. Sometimes this introduction to pride life occurs earlier, however, particularly if other lionesses have given birth at about the same time. If this occurs, once the cubs are past the initial stage of isolation with their mother, the cubs are then raised together, sometimes nursing communally, the cubs suckle indiscriminately from any or all of the nursing females in the pride.
  17. Lions usually hunt in groups. Young individuals begin to hunt effectively when nearing the age of two. A single lion iscapable of bringing down prey like zebra and wildebeest, which can be twice their own weight. Larger prey like giraffe needs teamwork. In prides, lionesses do most of the hunting. Prey is typically eaten at the location of the hunt, although large prey is sometimes dragged into cover. Lions can kill animals much larger than themselves. After a successful hunt, all the lions in the pride share the meal. But there is a pecking order, with the adult males taking first claim, followed by the lionesses, and finally, the cubs. When food is scarce, cubs tend to suffer the most but otherwise all pride members can eat their fill, including old and crippled ones which can live on leftovers. In the amazing video below, a lioness with an injured jaw gets help in eating a carcass from the other lionesses of the pride.

  18. An adult lioness needs to consume an average of about 5 kg (11 lb) of meat per day. Males are larger, naturally they need to eat more, about 7 kg (15 lb) per day. A lion may gorge itself and eat up to 30 kg (66 lb) in one sitting.
  19. Lions have the loudest roar of any big cat. A male lion’s roar can be heard from a distance of 8 kilometers (5 mile). The roar is usually used to advertise the animal’s presence. Lions do not purr. The largest cats that can purr are cougars (also called pumas, mountain lions, catamounts, Florida panthers, painters, ghost cats, etc). That’s why cougars are considered part of the lesser/small cat classification when it comes to their ability to purr and not roar.

  20. Lions are great swimmers. They can sometimes even hunt or chase their pray in the water, as seen in the BBC video below.

Bonus fact: Mountain lions (pumas, or cougars) are not lions. The term “Mountain lion”was first used in writing in 1858 from the diary of George Andrew Jackson of Colorado, a gold digger. A Missourian by birth, he worked in the California goldfields from 1853 to 1857. He headed to Colorado when gold was discovered here in 1858.

Some Not So-Amazing Lion Facts

  1. Lion has been listed as Vulnerable on the IUCN Red List since 1996, as populations in African range countries declined by about 43% since the early 1990s. Like most wild animals which share the same status, habitat loss and conflicts with humans are considered the most significant threats to the lion populations. They are mostly killed by humans in bravery rituals, as hunting trophies, for (non-existing!) medicinal powers, or by ranchers protecting their livestock. Estimates of the African lion population range between 16,500 and 47,000 living in the wild in between 2002–2004, down from early 1990s estimates that ranged as high as 100,000 and perhaps 400,000 in 1950.

Once widely distributed across most of Africa and parts of Europe and Asia, the lion is now confined to a number of isolated areas as shown on the map, amounting to only about 20% of its historic range. Two thousand years ago, over a million lions roamed throughout regions that covered Europe, Syria, Israel, Iraq, Pakistan, Iran, and India. In the 1940s, lions numbered 450,000. Today, estimates of the African lion population range between 16,500 and 47,000 living in the wild in between 2002–2004. Image: wikimedia
  2. Lions, especially in captivity, are also vulnerable to the domestic cat diseases like feline immunodeficiency virus (FIV) and feline infectious peritonitis (FIP). Furthermore, it was long believed that cats (both domestic and wild) were resistant to canine distemper, but it is now known that both large Felidae including lions, and domestic cats can be infected, usually through close housing with dogs.
  3. Lions do not have natural predators, but the majority die violently from humans or other lions. Crippled, sick or old lions and lion cubs may fall victim to hyenas, leopards, or be trampled by buffalo or elephants. During a fight, Lions often inflict serious injuries on each other. These fights occur either members of different prides encountering each other in territorial disputes, or members of the same pride fighting at a kill. When another group of male lions takes over a pride, they kill all the cubs. So they can sire their own with the lionesses.

  1. Panthera is a genus within the Felidae family that was named and first described by the German naturalist, botanist, biologist, and ornithologist Lorenz Oken (1 August 1779 – 11 August 1851) in 1816. The British zoologist and taxonomist Reginald Innes Pocock F.R.S. (4 March 1863 – 9 August 1947) revised the classification of this genus in 1916 as comprising the species lion, tiger, jaguar, and leopard on the basis of cranial features (for example, only these for have the anatomical structure that enables them to roar). Later, results of genetic analysis indicate that the snow leopard also belongs to the Panthera genus, a classification that was accepted by IUCN assessors in 2008.
