Claim check

Are lions the king of the jungle?

Not supported

No good evidence supports this, or the evidence points the other way.

Lions do not live in jungle. No male rules a pride — the females are the permanent members and the males are visitors who hold it for a few years. And lions lose carcasses to hyenas as well as taking them.

The claim as it circulates

“The lion is the king of the jungle — the apex predator that rules its territory and its pride.”

Taking it apart

What was claimed
That lions are the dominant animal of the jungle, and that a pride is ruled by a dominant male.
What was actually observed
Lions inhabit savannah, grassland and open woodland; they do not occur in rainforest. A pride comprises related adult females who remain in their natal range for life, together with a male coalition whose tenure is typically two to three years before displacement by another coalition. Incoming males kill unweaned cubs. Lions scavenge substantially, including taking carcasses from spotted hyenas, and carcass transfer runs in both directions depending on the relative numbers of each species present.
What the evidence supports
That lions are large-prey specialists at the top of their food web, and that a pride is a female kin group with a rotating male component.
What it does not support
Jungle, which is the wrong habitat. Rule, which describes neither the male's relationship to the females nor his tenure. And unchallenged dominance: enough hyenas will displace a lioness from a kill, and lions take at least as much from hyenas as the reverse.

The phrase probably comes from a mistranslation or a loose use of "jungle" to mean wilderness, and it has been wrong about habitat for as long as it has been used. Lions are animals of open country.

The kingship is wrong in a more interesting way. The durable part of a pride is the group of related females who were there before any given male arrived and will be there after he is displaced. A coalition holds a pride for a couple of years at most. If ownership is the frame, it runs the other way round.

And the hyena relationship has been known since the 1960s without ever reaching the popular account. Hyenas hunt successfully and lions steal from them frequently; the direction of theft is settled largely by numbers. The noble hunter and the thieving scavenger were a narrative choice rather than an observation.

The claims underneath

Each one carries its own evidence, scope and caveats. Expand any of them to reach the studies.

A pride is a group of related females; the males are visitors who hold it for a while

Established

Specialists would state this without hedging. Multiple independent lines of evidence agree.

A lion pride comprises related adult females and their dependent offspring, which forms the stable core, together with a coalition of one or more adult males whose tenure is temporary. Males disperse from their natal pride as adolescents and form coalitions, most often with brothers and cousins but sometimes with unrelated males; larger coalitions take over prides more successfully and hold them longer. In small coalitions reproduction is shared relatively evenly; in large ones it is more skewed. Incoming males kill unweaned cubs, which returns females to reproductive condition sooner, and females show counter-adaptations including birth synchrony, communal nursing in crèches, and mating during periods when conception is unlikely.

You may have heard

“A pride is ruled by one dominant male — the king — with his females”

The stable part of a pride is the females, who are related to each other and stay for life; the males are the transient element, arriving as a coalition and holding the pride for perhaps two to three years before being displaced. So the ownership runs the other way round from the story. And the takeover is not a change of management: incoming males kill the cubs, which is why female lions synchronise births, nurse each other's cubs and defend them collectively. Leaving that out makes everything else about pride life incomprehensible.

Why we rate it this way, and what the caveats are
EstablishedHigh confidence

Individual lions have been followed continuously in the Serengeti since the 1960s, so coalition formation, takeover, tenure and cub fate are recorded rather than inferred.

How far it can be extended

Female philopatry, male dispersal into coalitions, takeover and infanticide are documented across African lion populations, with Asiatic lions differing in that males associate with females only around mating.

Caveats

  • Most detail comes from one intensively studied population.
  • Relatedness in the early work was inferred from observed maternal history rather than genotyping.
  • Asiatic lions differ in social structure and are a small, separately managed population.

Still unanswered

  • What determines whether an unrelated male is accepted into a coalition, given that reproduction is then shared with a non-relative?

The evidence (3 studies)

They specialise on large prey — and steal a great deal of it from hyenas

Established

Specialists would state this without hedging. Multiple independent lines of evidence agree.

Compiled kill records across African study sites show lions preferentially taking prey in a band of approximately 190 to 550 kilograms, with a most-preferred mass near 350 kilograms, and avoiding much smaller and much larger species relative to availability. The preference holds across sites with differing prey communities. Lions also scavenge substantially, including taking carcasses from spotted hyenas; carcass transfer occurs in both directions and depends on the relative numbers of each species present.

You may have heard

“Lions are noble hunters and hyenas are scavengers that steal their kills”

This has been backwards since it was first checked in the 1960s, and the correction is still not widely known. Lions scavenge a great deal, including taking carcasses from hyenas — which hunt successfully and often. Transfer runs both ways and is settled largely by numbers: enough hyenas will displace a lion, and a coalition of males will displace any number of hyenas. The moral framing came from documentaries rather than from field records.

Why we rate it this way, and what the caveats are
EstablishedHigh confidence

A cross-site compilation in which the same preference emerges from independent prey communities, supported by decades of direct observation of carcass acquisition.

How far it can be extended

Prey preference was consistent across sites with substantially different prey communities, which is what distinguishes a predator property from local availability.

Caveats

  • Kill records under-represent small prey, which are consumed quickly and rarely observed.
  • Compiled from studies with differing methods and detection biases.
  • The direction of carcass transfer between lions and hyenas varies with local densities of each.

Still unanswered

  • What proportion of a lion's intake is scavenged rather than hunted, across systems with different scavenging opportunity?

The obvious explanation for why lions live in groups was tested in the Serengeti, and it was wrong.
