Quick verdict
Start with the direct answer, then use the structured comparison below to see what changes the outcome.
The black-and-white ruffed lemur takes this one, though not by much. Both are mid-sized Madagascar lemurs weighing roughly 3–4.5 kg, so neither has a big mass edge. The ruffed lemur wins because of how it is built and how it behaves. It is a quadrupedal canopy runner with strong grasping limbs and a loud, assertive temperament: its group 'roar-shrieks' are among the loudest primate calls in Madagascar. Coquerel's sifaka is a specialist vertical clinger and leaper. Its long, powerful hind legs are superb for springing between trunks and for bounding sideways across open ground. They are less suited to the close, grappling, branch-level scuffles where the ruffed lemur's all-four-limbs dexterity matters most. Lemur conflicts are usually short bursts of display, cuffing and chasing rather than prolonged fights. In that kind of contest, the ruffed lemur's bolder posture, slightly higher speed rating and comfort moving horizontally through dense canopy give it the edge more often than not. The sifaka's best answer is evasion, and evasion doesn't win a confrontation.
Read the full explanation
Winner: Black-and-white Ruffed Lemur, a narrow edge driven by temperament and four-limbed canopy agility.
Size is nearly even. Both species fall in roughly the 3–4.5 kg range, so build and behavior decide it.
The sifaka's leaping legs are elite for escape and open-ground bounding, but less useful in a grappling scuffle.
Most real encounters would end in display and retreat, not injury.

Editorial note
Why people disagree
Sifakas look athletic in their famous sideways 'dancing' hops, so people assume that explosive leg power translates into fighting power. It mostly translates into mobility.
Body mass and frame
The weights overlap. The ruffed lemur's mass is spread for grappling and pushing, which suits close contact better.
Explosive leg power
The sifaka can launch away almost instantly, which makes it very hard to pin down.
Branch-level control
Most scuffles happen in tangled branches, which is the ruffed lemur's home terrain.
Read the full explanation +
Both species are similar in weight, which makes any verdict feel like a coin flip. Readers weigh temperament differently.
They don't share ranges in the wild: ruffed lemurs live in eastern rainforest, Coquerel's sifakas in northwestern dry forest. That leaves no real-world encounters to settle the argument.
Comparison FAQ
Short, direct answers to the next questions readers usually ask after the headline verdict.
Would a black-and-white ruffed lemur beat a Coquerel's sifaka in a fight?+
Usually, yes, but narrowly. In canopy terrain the ruffed lemur's grip, sturdier frame and assertiveness give it the edge. Most real encounters would end with display and retreat rather than serious injury.
Which is stronger, a ruffed lemur or a sifaka?+
They are similar in weight. The sifaka has more explosive leg power, while the ruffed lemur has better all-around limb strength for grappling. For fighting purposes, the ruffed lemur's strength is more usable.
Why is the Coquerel's sifaka still dangerous to the ruffed lemur?+
Its powerful legs let it strike and leap away in an instant, and it has sharp canines like all lemurs. On open ground or among spaced trunks, it controls distance and can't be cornered easily.
Do ruffed lemurs and sifakas meet in the wild?+
Not these two. Black-and-white ruffed lemurs live in eastern Madagascar's rainforests, while Coquerel's sifakas live in the northwestern dry forests.
Which one is rarer?+
Both are threatened. The black-and-white ruffed lemur is listed as Critically Endangered, and Coquerel's sifaka is Critically Endangered as well. Habitat loss is the real threat to both, far more than any rival.

Verdict confidence
82%
Ruffed lemur controls the tangle.
Among dense, horizontal branches, the ruffed lemur can brace with all four limbs, and even hang by its feet. That frees its hands and teeth for cuffing and biting. The sifaka is built to cling vertically and leap. In cluttered terrain its biggest asset loses room to work, and the more assertive ruffed lemur dictates the exchange.

Final take
The black-and-white ruffed lemur is the overall winner of this matchup. Its advantage isn't raw size, because the two are nearly identical in weight. It comes from a body and temperament suited to close, branch-level conflict: four-limbed grip, a sturdier upper frame, and one of the loudest, boldest display repertoires in Madagascar.
Read the full explanation
Coquerel's sifaka is no pushover. Its spring-loaded legs make it one of the most agile primates on Earth, and in open ground or spaced-trunk forest it decides whether a confrontation happens at all. But a mobility edge is an escape edge. In the cluttered canopy where these animals actually live and feed, the ruffed lemur's commitment usually decides who keeps the branch.

Black-and-white Ruffed Lemur vs Javan Slow Loris: Who Actually Wins?
The Black-and-white Ruffed Lemur wins this one. At roughly 3.1–4.5 kg, it carries about five to six times the mass of a Javan Slow Loris (around 0.6–0.7 kg). It is also a fast, explosive leaper built for daylight canopy travel, while the loris is a slow, grip-locked climber. The loris is not harmless. It is one of the very few venomous mammals, mixing a secretion from glands on its upper arm with saliva to deliver a toxic bite through its sharp toothcomb. That bite can cause painful, slow-healing wounds. But venom delivered at loris speed has to land first. A heavier, faster animal that controls distance, reach, and the timing of contact holds most of the decisive levers. In nearly every realistic frame, the lemur either overpowers the encounter or simply refuses it, and the loris has no tool to force a fight on its own terms.

Coquerel's Sifaka vs Four-horned Antelope: Who Actually Wins?
The Four-horned Antelope wins this matchup clearly. It weighs roughly 17–22 kg against the sifaka's 3.5–4.5 kg, so it carries about four to five times the body mass. Males also have the only four-horned skull among living wild bovids: two short front spikes and two sharper rear horns of about 8–10 cm. The sifaka is a superb leaper, launching up to around 10 m between trunks, but its body is built for vertical clinging and gliding leaps, not for absorbing a butt or holding ground. On the forest floor, in open scrub, or at a waterhole, the antelope's mass, hooves and horn tips decide the encounter. The sifaka's real 'win condition' is to leave by going up a tree. That is a survival success, not a fight victory.

Black-and-white Ruffed Lemur vs Golden-headed Lion Tamarin: Who Actually Wins?
The Black-and-white Ruffed Lemur wins this matchup clearly. At roughly 3.1–4.5 kg it outweighs the Golden-headed Lion Tamarin (about 0.5–0.7 kg) by around six to eight times. In small primates that gap decides almost every physical contest. The lemur's longer limbs, stronger grip, bigger jaws, and loud group defense mean a tamarin cannot overpower it, hold its ground against it, or drive it away from a shared fruit tree. The tamarin's real edges are being quick and agile, slipping through tangles, and staying alert. Those help it avoid a confrontation, but they don't help it win one. In any frame where the two actually have to settle something, the lemur's mass and reach decide it.

Coquerel's Sifaka vs Ring-tailed Lemur: Who Actually Wins?
Coquerel's Sifaka takes this one, but narrowly. At roughly 3.7–4.3 kg it outweighs the 2.2–3.5 kg Ring-tailed Lemur. Its long, powerful hind legs are built for explosive vertical leaping, and those springs translate into shoving force and fast repositioning in trees. The Ring-tailed Lemur is quicker on the ground, more socially strategic, and has sharp wrist spurs and stink-fighting tactics. In any physical clash, though, the sifaka's mass, reach and leg-driven power are hard for the smaller lemur to overcome. Neither species actually hunts the other, so this is a dominance contest rather than a predator showdown. The edge goes to the sifaka, with real upset potential on open ground.
