What are the adaptations of a lion?

On the African plains at dawn, three lionesses spread out in the long grass. One circles left, one circles right, and one waits low in the middle. The zebra herd has no idea it is being surrounded.

Lion adaptations are mostly about teamwork. Lions are the only big cats that live in groups, called prides, of 3 to 30 lions, says San Diego Zoo Wildlife Alliance. Lionesses stalk prey together from several sides. A short sprint, a roar heard up to 8 km (5 mi) away and a body that saves water help too.

What are the three types of lion adaptations?

Lion adaptations come in three kinds. Structural adaptations are body parts, like the mane, claws, teeth and eyes built for open plains. Physiological adaptations are how the body works, like getting water from prey and eating huge meals. Behavioural adaptations are what lions do, like living in prides, hunting as a team, roaring and resting most of the day.

For the difference between the three kinds, see our guide to behavioural, structural and physiological adaptations.

What are the structural adaptations of a lion?

A lion’s main structural adaptations are eyes with a horizontal band of nerve cells for watching open plains, sharp claws and teeth, a big, heavy body that can pull down buffalo and zebra, and, in males, a mane that signals health. Lions are built for a short, powerful rush, not a long chase.

How are a lion’s eyes, claws and teeth built for hunting?

A lion’s eye has a horizontal band of nerve cells that improves its view of prey moving across a plain, says San Diego Zoo. Lions also track prey by scent; see how far a lion can smell. For the power behind the final grab, see how strong a lion is.

Why do lions have manes?

Charles Darwin guessed that the mane protects a male’s neck in fights. Scientists in Tanzania’s Serengeti tested this. Wounds to the mane area were no more common or deadly than wounds elsewhere, reports Peyton West in American Scientist. So the shield idea did not hold up.

Instead, the mane works like a signal. Males with darker manes had more testosterone and were better fed through the year. In 13 out of 14 cases, females mated with the male that had the darkest mane in his group.

A dark mane has a cost: heat. Males in cooler places grow darker manes than males in hot, humid ones. In Kenya’s Tsavo National Park, where it is hot, many males have very short manes, or almost none.

How big are lions?

Size is an adaptation too. Males weigh 150 to 260 kg (330 to 570 lb) and females 122 to 180 kg (270 to 400 lb), says San Diego Zoo Wildlife Alliance. That weight lets a pride pull down buffalo and zebra.

What are the physiological adaptations of a lion?

A lion’s key physiological adaptations are a body that can go long periods without drinking by getting moisture from prey, as Kalahari lions do, and a stomach that can take up to about 63 kg (140 lb) of meat in one meal. Both let lions survive in dry places where kills and water holes are far apart.

How do lions survive without much water?

Where water is easy to find, lions drink often. But in the Kalahari Desert, lions can live without drinking for long periods. A study by Fritz Eloff found that they get enough moisture from the blood and body fluids of their prey, plus some plant parts, as described in Koedoe (1973). Resting through the hottest hours also means a lion loses less water by panting, Eloff found.

How much can a lion eat at once?

A male can eat about a quarter of his body weight, up to about 63 kg (140 lb), in one meal, says San Diego Zoo. That is about the weight of a grown man. Then the lion lies down to digest it.

What are the behavioural adaptations of a lion?

A lion’s main behavioural adaptations are living in prides, stalking prey as a team from several sides, roaring to warn rivals and keep in touch, defending territory and cubs together, and resting about 21 hours a day. Working as a group lets lions take on prey far bigger and more dangerous than a lone cat could.

Why do lions live in prides?

A pride is built around related females, their cubs and one or more adult males, says the Smithsonian’s National Zoo. Prides can have as many as 40 members.

Group life lets lions tackle big, dangerous prey. Cape buffalo are large, and hunting them takes weight and strength more than speed. Male lions are very capable buffalo hunters, and one buffalo can feed a big pride, notes Peyton West in American Scientist.

Prides also defend territory and cubs. Males fight hard to keep control of a pride, and they pay for it: wild lionesses may live to 16, but males rarely live past 12, says the Smithsonian. Our page on what eats lions explains the dangers cubs face.

How do lions hunt together?

Lions are not built for long chases. So several lions may stalk prey from different angles to within about 30 m (100 ft) before they attack, says the Smithsonian. When they finally rush in, a lioness can reach 53 km/h (33 mph), says San Diego Zoo Wildlife Alliance. Compare that with other cats in how fast a tiger can run.

Why do lions sleep so much?

Lions rest for about 21 hours in every 24, says San Diego Zoo. Hunting takes short bursts of huge effort, and kills do not come every day. Resting saves energy for the next hunt and, in dry places, saves water.

Why do lions matter to the savanna?

Lions are top predators. By hunting large plant-eaters such as zebra and buffalo, they help keep those herds from growing too big for the grass and water available. The meat they leave behind also feeds scavengers. Lions sometimes even kill and eat other lions; see will a lion eat another lion?

Are lions endangered?

No adaptation protects lions from people. Lions are listed as Vulnerable, with about 22,000 to 25,000 left in Africa and just under 700 in India, says San Diego Zoo. Compare lions with their Asian cousins in tiger adaptations, and with the speed specialist in cheetah adaptations.

Myths about lion adaptations

Myth: The mane is a shield that protects a male’s neck in fights.

Fact: In the Serengeti, wounds to the mane area were no more common or deadly than wounds elsewhere. The mane is mainly a signal of health (West 2005). Why people believe it: Charles Darwin suggested the shield idea.

Myth: Lions chase prey down over long distances.

Fact: Lions stalk to within about 30 m (100 ft), then make a short rush (Smithsonian).

Myth: Lions are lazy because they sleep all day.

Fact: Resting about 21 hours a day is an adaptation. It saves energy for short, hard hunts and saves water in dry places.

Test yourself

1. Is living in a pride a structural, physiological or behavioural adaptation?

Behavioural, because it is something lions do.

2. How do Kalahari lions get water when there is none to drink?

From the blood and body fluids of their prey, plus some plant parts (Eloff 1973).

3. What does a dark mane tell lionesses?

That the male has more testosterone and is well fed. Lionesses preferred dark-maned males.
