A massively powerful animal, the African Lion weighs in the range of four hundred and fifty to five hundred and fifty pounds for healthy adult males whereas females are usually in the range of three hundred to three hundred and fifty pounds. Length is between six to eight feet for males and five to six feet for females, excluding a near three foot tail. Significantly bigger individuals have been recorded though. The largest wild lion ever weighed was close to seven hundred pounds. In captivity a specimen of well over eight hundred pound is documented. Height at shoulders is close to four feet for males and three and a half feet for females.
The lion’s coat is tawny in coloration and plain. Fur is short and somewhat coarse. Males are distinguished by their big mane that covers head, neck and part of belly and back. The mane is pale in coloration initially and goes through shades to golden to black as the lion ages. A black colored full mane signifies a mature lion with good breeding potential and is often preferred by lionesses for a partner.
In some parts of Africa, including Senegal and notably Tsavo, Kenya, maneless male lions are recorded, possibly in adaptation for the thorny habitat of that regions. Overall the built is muscular for both sexes. Lionesses are more athletic since it allows them to excel in hunting, their primary role in the pride. Male lions are bulkier since the added weight and strength allows them to fight off intruders and defend the pride’s territory.
Weapons include sharp claws and near three inch canines. Jaws are powerful and skull is bigger than any other cat specie. Eyes are set in front as in case of most land predators rather than on sides as in case of prey. The field of vision that is so essential for prey animals to look out for hunters comes with widely set eyes. This visual field is compromised in favor of better depth perception and binocular vision in lions that comes with relatively narrowly placed eyes, that aid them in judging distance from prey for pouncing upon it. Tail has a tuft of hair that covers the spine at the tip of tail. Belly skin is loose and shields the internal organs from viscous kicks of hunted ungulates during a kill.
Social cats, African Lions are apex and keystone predators. They live and hunt together, increasing the chances of success and survival for themselves and their cubs during harsh seasons. Lionesses do the bulk of hunting by laying a sort of organized trap for the hunted. Each lioness performs a specific role in this form of group hunting. Usually the weak and old are chosen and isolated from the herds. Then one or two lionesses expose themselves by breaking cover and charging at prey. The panicked animals take off and usually end up in jaws of a waiting lioness in their flight. A suffocating hold is placed by biting at the neck of smaller prey or covering the mouth and nose of larger prey.
In contrast with previous beliefs, it is now estimated that male lions take part in up to fifty to sixty percent of all hunts, being of particular use in taking down larger prey like buffalo. Other animals taken are of a vast variety depending upon the type and abundance of prey animals in a particular territory. These include eland, gemsbok, hartebeest, impala, kudu, warthog, wildebeest and zebra. At times even giraffes and the young of rhinos, hippos and elephants are killed. Opportunistic predators, lions will hunt and eat anything in times of need including carrion. Some lions in Botswana have been filmed killing elephants after a period of severe drought. Calves were regularly taken and occasionally so were adults under cover of darkness.
African Lions are at the top of food chain in African Savannah and do not refrain from wiping out competition if opportunity presents. Conflict with spotted hyenas are common who are often able to intimidate lionesses and cubs owing to their greater numbers, but suffer heavily when they come in contact with males. Adult male lions have been witnessed displaying rather savage behavior towards hyenas on occasions, actively chasing and killing off adult and the young of hyenas. At times lions have been recorded scavenging off hyena kills. Interspecies conflict with other big cats also occurs and African Lions often kill leopards and cheetahs and their young, possibly to ward off competition.
A number of subspecies of lions are recognized, based upon their area of distribution in Africa.
Panthera Leo Azandica (North East Congo lion) – North-eastern Congo
Panthera Leo Bleyenberghi (Southwest African or Katanga lion) – South-western Africa, Namibia, Botswana, Angola, Katanga (Zaire), Zambia and Zimbabwe
Panthera Leo Krugeri (Southeast African or Transvaal lion) – Transvaal region of South eastern Africa, including Kruger National Park
Panthera Leo Nubica (East African or Massai lion) – East Africa from Ethiopia and Kenya to Tanzania and Mozambique
Panthera Leo Senegalensis (West African lion) – Western Africa from Senegal to Nigeria
Territorial cats, African Lions live in pride areas of up to tens of square miles depending upon the concentration of lions and prey in a particular region. Males regularly patrol the territory, marking it with scent from their paws and urine. At dusk and dawn they roar to establish their presence and warn off intruders. The roar is loudest among cats and can be heard up to a distance of five miles. A pride consists of one to four males and up to a dozen or more of females and young cubs. Females are generally related to each other and usually stay in a pride for the duration of their life whereas young males are kicked off by adults when they are between two to three years old. These young males then pursue a nomadic lifestyle, forming coalitions with other solitary males and hunting and surviving on their own. When they are four to five years old they are capable of taking over a pride of their own.
Next they move into the domain of resident males of an established pride and attempt to take over the territory and lionesses. This often results in a bloody and at times fatal battle. If the resident males lose out, they slink away and the nomads are quick to kill any cubs sired by previous males. This brings the females into estrus. The new males also kill or drive away any young males. The take over is often brutal and sometimes takes months.
After the lionesses have finally settled down, the new males have only a period of two to three years on average to produce cubs of their own that can successfully reach adulthood and propagate their genetic line before they are ousted as well. Females come into estrus year round and produce a litter of two to three cubs after a pregnancy lasting between three to four months. The young learn hunting by one year and are fully independent by two years of age. Maturity is reached by four years in females and five years in case of males. Lifespan is between twelve to fifteen years in the wild and around twenty five years in captivity.
