Quick verdict
Start with the direct answer, then use the structured comparison below to see what changes the outcome.
The yacare caiman wins, and usually by a wide margin. An adult yacare is a 2–2.5 m, 30–60 kg armored predator with osteoderm-plated skin, a crushing bite and a feeding apparatus built to seize and shake struggling prey. The false water cobra is an impressive snake, often 2–2.8 m, fast, alert and capable of a dramatic hooded neck-flattening display. But it is rear-fanged, and its mildly venomous saliva is delivered by chewing, which works on frogs and fish. It does not stop a large crocodilian. It also cannot constrict a caiman. Matched as adults, the caiman's mass, armor and grip-and-thrash bite decide the encounter. The snake's real winning move is to leave quickly, and in the Pantanal yacare caimans do eat snakes when given the chance.

Overall winner: Yacare Caiman, with high confidence.
Armor plus bite force beats the cobra's speed and rear-fanged venom.
The false water cobra's venom suits small prey and is poorly delivered against thick, plated skin.
The snake's best outcome is escape. Only juvenile caimans are realistic prey for it.

Editorial note
Why people disagree
The name 'cobra' makes people assume deadly venom. Hydrodynastes is not a true cobra, and its venom is mild and slow to deliver.
Explosive power
The caiman's snap lands with far more mass behind it, so one connection can end the exchange.
Weapon system
Rear-fanged venom needs sustained contact. A caiman bite causes immediate damage.
Close-range durability
Armor blunts the snake's only offense, while the snake has no protection from crushing jaws.

Length looks equal on paper, but a heavy-bodied crocodilian outweighs a slender snake many times over.
Big snakes eat caimans in viral clips, but those are anacondas, which are constrictors of a different weight class.
Comparison FAQ
Short, direct answers to the next questions readers usually ask after the headline verdict.
Would a false water cobra beat a yacare caiman?+
No. An adult yacare caiman would almost always win a real fight. The snake's realistic victory is escape.
Which is stronger, the false water cobra or the yacare caiman?+
The yacare caiman, by far. It is many times heavier, armored, and has a much more powerful bite.
Is the false water cobra's venom dangerous to a caiman?+
Not meaningfully. It is a mild, rear-fanged venom that has to be chewed in, and it suits small prey. Caiman armor makes delivery even harder.
Why is the false water cobra still dangerous?+
It is large, quick and willing to bite repeatedly. It can injure a juvenile caiman and may bluff a larger one into hesitating. To humans, a bite is painful and can cause swelling.
Do caimans eat snakes?+
Yes. Yacare caimans are opportunistic and will take snakes, including large ones they can overpower.

Verdict confidence
82%
The caiman's home turf decides it.
A yacare lies submerged and waits. When the snake swims close, the sideways snap and grip-and-roll take over. The cobra's chewing venom cannot work while it is being shaken and held under water.
