Lion, member of the cat family whose size, power, and bearing have
captured human imagination since earliest times. Called the king of
beasts, lions once ranged throughout Africa and from Europe to Iran and
India. By 1900 lions were no longer found in Syria; today Eurasian wild
lions are limited to the Gir Sanctuary in India. Lions also roam Africa
south of the Sahara, particularly the Serengeti National Park in
Tanzania and the Kruger National Park in South Africa. This drastic
reduction in range came about as human beings and domestic livestock
spread into savannah lands. Because lions live in open areas, they are
easily shot by hunters and herders. In sanctuaries, however, they are a
great attraction for tourists, and within such confines their survival
is not endangered except by disease.
Lions have relatively short-legged, long, muscular bodies and large
heads. The male grows to 1.7 to 2.5 m (5.6 to 8.2 ft) long, not
including the tail, which is 90 to 105 cm (36 to 41 in) in length. The
animal stands 1.23 m (4 ft) high at the shoulder, and it weighs 150 to
250 kg (330 to 550 lb). The mane, which covers the head and neck,
sometimes extends to the shoulders and belly. It varies in length and in
colour, from black to tawny; well-fed, healthy lions have longer, fuller
manes. The smaller, equally muscular females are of the same tawny
colour but lack manes. Both sexes have hooked claws, which are
retractable (can be withdrawn), and wide, powerful jaws. The lion s
roar, which can be heard up to 9 km (5.6 mi) away, is usually uttered
before the animals hunt in the evening, after a successful hunt, and
again in the early morning. In the open savannahs they inhabit, lions
need travel only about 8 km (5 mi) and spend only two to three hours a
day in pursuit of food, passing the remaining hours resting and
sleeping. Lions do not hunt every day.
Social Organization
Among the most gregarious of the cats, lions associate in groups of one
or more family units called prides. A pride has 5 to 37 members composed
of 4 to 12 adult females, their cubs, and 1 to 6 adult males. The
females, which represent several generations, rarely leave the pride.
Male cubs stay in the pride until they are expelled when nearly adult.
They then roam about for several years, after which they begin to
contend with rival males to head a pride. Many males often remain
nomadic, and even those that take over a pride remain with the females
for only a few months to a few years before they leave on their own or
are forced out by rivals. When a male lion takes over another s pride he
takes over the territory and the females within it. He will often kill
some of the existing cubs that were fathered by the dominant male lion
that he defeated. A pride frequently breaks up into groups that later
recombine into different assemblages of individuals. In prides of Indian
lions the adult males are not resident.
The size of the territory that a lion pride works depends on the amount
of available prey in the territory, which may range in area from 20 to
400 sq km (8 to 150 sq mi). Lions of both sexes maintain territories by
leaving a strong scent on bushes and by roaring to warn off wandering
prides and nomadic males.
Predatory Behaviour
The prey of lions ranges from insects to giraffes; the animals prefer
large animals such as zebra. Hunting takes place in the evening and is
primarily a female group activity. The lionesses cautiously stalk their
prey and cut off escape routes. Once within close range, they run it
down in sprints reaching about 50 to 60 km/h (30 to 37 mph). The
lionesses great weight and momentum usually bring down their victims,
which are then dispatched with a bite to the throat that suffocates the
prey. After the female has made a kill, the male comes to share the
meat. Males may scare off females in order to take some of the meat. A
lion may eat 40 kg (88 lb) of meat at one time and then go for more than
a week before the next kill.
Reproduction and Life Span
Lions are polygamous (have more than one mate) and breed every 18 to 26
months in the wild; captive lions breed every year. After a gestation
period of about 110 days, one to four cubs are born, with thick, spotted
coats. Lions in captivity can live up to 20 years; in the wild, males
live an average of 12 years and females an average of 16 years.
Scientific classification: The lion belongs to the family Felidae. It is
classified as Panthera leo.
