Subspecies
Africa:
P.l.leo P.l.azandica P.l.bleyenberghi P.l.krugeri P.l.nubica
P.l.senegalensis
Asia: P.l.persica.
Life span
Lions live
for 12-16 years in the wild and 25 years in captivity.
Size
Body length:
170-190cm Tail length: 70-150cm Shoulder height: 80-110cm Weight: male:
150-225kg, Female: 120-150kg. Males are much larger than females and can
be 50 per cent heavier.
Physical
Appearance
Lions vary in
colour from nearly white to deep ochre brown but tawny yellow is the
commonest shade. Male lions develop thick woolly manes on the neck and
shoulders, signifying maturity. The mane protects the lion during fights
with other males. It also differentiates between genders from a distance
across savanna plains and is an indicator of fitness. Lions are the only
cats to have a mane, suggesting it is linked to their unusual social
system.
Lions are also the only cats to have a tuft at the end of their tail.
Cubs are born with spots, which disappear as they get older, although the
spots sometimes persist on their legs and belly.
Distribution
Formerly lions
roamed most of Africa. Now their distribution is patchy and they are only
found in reserves and national parks south of the Sahara and in the Gir
Forest, India.
Habitat
Lions are
quite adaptable and can be found living on desert fringe, in woodland or
open savanna, but are absent from equatorial forests.
Diet
Lions hunt by
ambush. Their main prey includes medium to large-sized mammals such as
antelope, buffalo, zebra, giraffe, warthog and deer, but they will also
scavenge for food. Asiatic lions in particular also prey on domestic
cattle. Lions can survive for long periods without water, obtaining
moisture from prey and plants.
Social
organisation and behaviour
Lions live in
groups called 'prides'. The pride may consist of up to twelve related
adult females and their young, and up to six adult males who are probably
related to each other but not to the females. Prides can range from 3-30
individuals, but average 4-6. Theories as to why lions live in social
groups include increased hunting success, defence of young, maintenance of
long-term territories, insurance against individual injury and
minimisation of chances of getting no food at all.
Of all the big cats, the lion is the only one which relies extensively on
group co-operation. Lionesses tend to stay in the pride they are born in.
This makes the group a collection of sisters, aunts, mothers and
grandmothers who have grown up together. Males are expelled from the pride
that they are born in once they reach maturity. They usually form
coalitions with other males (often relations) with whom they hunt and
scavenge for food.
Females tend to do most of the hunting for the whole pride. They hunt
cooperatively, each individual taking on a different role. The larger
lionesses tend to ambush prey which the females on the wings chase in her
direction. Lions usually hunt at night.
Male lions defend the pride against intruders. They mark key points of the
territory with urine and patrol the boundaries regularly, roaring to warn
other lions of their presence. Competition between males to head a pride
is fierce, and males tend to hold ownership for only 2-3 years. Fights for
possession of a pride are vicious and may result in serious injury or
death.
Reproduction
Females will
tend to come into oestrus simultaneously and thus most of the cubs are
born at the same time. Lionesses give birth to 2-5 cubs, after a gestation
period of 100-116 days. The cubs are cared for by all the females in the
pride, and will suckle from other females as well as from their mother.
14-73 per cent of all lion cubs die before they reach the age of two
(varies according to location). A new male in a pride will kill all the
cubs which has the effect of bringing the females into oestrus. This means
that only he will be the father of the cubs in the pride.
Conservation/status
African lions
are not listed by the IUCN but are on CITES: Appendix II. The Asiatic lion
(P.l.persica) is on Appendix I and the IUCN class it as Endangered.
Threats include hunting, loss of habitat and human encroachment.
Notes
One of the few
animals that will attack lions are hyenas, which will kill an injured
lion, or if food is scarce, will occasionally attack a healthy one. Lions
and hyenas also have been known to kill each other in fights over prey.
