Lion

Lion facts at a glance

How big is a lion?

An adult lion measures 2.5 m long — about 1.4× the height of an average adult person (1.73 m) — and weighs around 250 kg, about 3.6× an average adult’s body weight (70 kg).

Behavior and social structure

Lions are the most social of all big cats, living in prides of related females, their cubs, and a small coalition of males. Females do most of the hunting and stay with the pride for life, while males defend the territory and the pride's borders. Lions can rest for up to 20 hours a day, conserving energy for short, explosive hunts at dawn and dusk.

Diet and hunting

As apex predators, lions hunt large herbivores such as zebra, wildebeest, buffalo, and antelope. They are the only cats that hunt as a coordinated team, using teamwork to surround and ambush prey. A single lion can eat up to 40 kg (88 lb) of meat in one sitting.

Habitat and range

Most wild lions live in sub-Saharan Africa across savannas, grasslands, and open woodlands. A separate, critically small population of Asiatic lions survives only in India's Gir Forest National Park. Lions avoid dense rainforest and true desert.

Conservation

Lion numbers have fallen by roughly half over the past 25 years, driven by habitat loss, conflict with livestock farmers, and declining prey. They are listed as Vulnerable by the IUCN, and the Asiatic subspecies is Endangered. Protected reserves and community conservation programs are central to their survival.

Communication and roaring

Lions have one of the most far-reaching calls of any land animal. A full roar can be heard up to 8 km (5 miles) away and is used to advertise territory and locate pride members. They also communicate through scent-marking, head-rubbing, and a range of grunts and growls that reinforce the social bonds of the pride.

Reproduction and cubs

Lionesses in a pride often give birth around the same time and raise cubs communally, even nursing one another's young. Cubs arrive after a gestation of about 110 days, weigh roughly 1.5 kg at birth, and are hidden away for the first weeks before joining the pride. When new males take over a pride, they may kill existing cubs to bring the females back into breeding condition.

Did you know? Lion facts

• A lion's roar can be heard up to 8 km (5 miles) away and is used to advertise territory and locate pride-mates.
• Lions are the only truly social cat, living in prides of related females, their cubs, and a coalition of males.
• Lionesses do most of the hunting, often in coordinated roles, while males defend the territory.
• Male tenure over a pride averages only about 2–3 years before being displaced by a rival coalition.
• Cubs are vulnerable to infanticide when incoming males take over a pride, which returns females to breeding condition sooner.
• The Asiatic lion survives as a single wild population in and around Gir, India.
• Lions can rest for 16–20 hours a day, conserving energy for short, explosive hunts at dawn and dusk.

Diet & feeding

Lions prefer medium-to-large ungulates in roughly the 190–550 kg range, such as blue wildebeest, plains zebra, and African buffalo (Hayward & Kerley 2005). A single lion can consume up to 40 kg of meat in one sitting, and prides routinely contest carcasses with hyenas and leopards.

Adaptations

• The male's mane signals fighting ability and condition, and may cushion bites to the neck during male–male combat. (West & Packer 2002)
• Powerful forequarters and retractile claws are built for grappling and subduing large prey at close range.
• A reflective tapetum lucidum supports low-light vision for hunting at dusk and night. (Nowak 1999)
• Specialised laryngeal and hyoid anatomy typical of Panthera enables the far-carrying roar. (Schaller 1972)
• Social carnivory lets lions take larger prey and defend kills — an uncommon strategy among cats.

Behaviour & ecology

• Prides defend ranges and repel unfamiliar lions; territory is strongly contested. (Packer et al. 1990)
• Lionesses hunt cooperatively, with coordination increasing on large prey and at night. (Stander 1992)
• Males may commit infanticide after a pride takeover, accelerating females' return to estrus. (Packer & Pusey 1984)
• Activity becomes more nocturnal near human settlement to reduce conflict. (Valeix et al. 2012)
• Females may synchronise breeding and nurse one another's cubs (allo-suckling). (Schaller 1972)

Communication

• Roaring advertises territory and locates pride members over several kilometres. (Schaller 1972)
• Scent-marking by urine spraying, scraping, and communal latrines reinforces boundaries.
• Head-rubbing and social licking strengthen bonds and transfer group scent.
• A graded set of grunts, growls, snarls, and moans coordinates movement and signals mood.

Habitat & range

Lions occupy savanna, grassland, and open woodland across sub-Saharan Africa, plus a single Asiatic population in India's Gir Forest. They avoid dense rainforest and true desert, favouring mosaic landscapes with cover for ambush and access to large herbivore prey.

Ecological role

As an apex predator and keystone species, the lion exerts top-down control on herbivore populations and behaviour, removes vulnerable individuals, and provisions carrion to scavengers — shaping the structure of savanna food webs.
