Lion adaptations: how lions hunt, share and survive

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.

Lion adaptations at a glance

Lions live on open plains, in thick brush and in dry thorn forest. The table lists the main traits that help them there, with the numbers behind each one.

Why do lions live in prides?

A pride is a family business. It 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 slow, 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 lion researcher Peyton West in American Scientist. A lone cat could not safely take on animals that size.

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 lion can cover the length of a football field in about six seconds, and a lioness can reach 53 km/h (33 mph), says San Diego Zoo Wildlife Alliance.

Their eyes help on open ground. 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, even in females, which have no mane, 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. Lionesses noticed. 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 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).

Their lazy style helps too. Resting through the hottest hours means a lion loses less water by panting, Eloff found. That links to the next adaptation: sleeping most of the day.

Why do lions sleep so much?

Lions rest for about 21 hours in every 24, says San Diego Zoo Wildlife Alliance. 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.

When food does come, lions fill up. 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 like eating a whole grown man’s weight of meat. Then the lion lies down to digest it.

How big are lions, and are they endangered?

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.

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.
