Quick Take
- Megalodons are extinct marine apex predators.
- Great white sharks are modern-day marine apex predators.
- Megalodons were much larger, but slower, than great white sharks.
The battle of old versus new appears in many forms, and the concept of a fight between the megalodon (Otodus megalodon) and a great white shark (Carcharodon carcharias) is an interesting one. The megalodon lived 3 to 3.6 million years ago and was an apex predator that reigned for about 20 million years before becoming extinct due to climate change and increased competition for fewer resources.
The great white shark is an apex predator, occupying the top of the marine food chain with no natural predators except for occasional orca predation. Like a boxing match between today’s greats and the heroes of the past, we can’t help but wonder which of these two predators would come out on top in a fight.
In a hypothetical fight between the ocean’s most successful predators, the key factors to consider are size, speed, bite force, defenses, offenses, and predatory behavior. Continue reading to discover who wins in a fight between these formidable opponents in a match that spans millennia.
Megalodon vs. Great White: Size
The great white shark is one of the largest predatory fish in the ocean today. Great white sharks typically range between 15 and 18 feet long, but can reach up to 21 feet and weigh as much as 4,500 pounds. However, the great white’s size pales in comparison to the megalodon, a massive shark that weighed 100,000 pounds and grew to a maximum of almost 49 feet.
Size Advantage: Megalodon

Megalodon vs. Great White: Speed and Movement
Speed and movement are two important factors in determining who wins a fight. The faster the predator, the better chance it has of landing the initial strike. The great white has a top speed of 25 miles per hour (mph).
Recent research suggests megalodon cruised at between 3 and 3.5 mph, but may have been capable of short bursts up to 11 mph or more. Therefore, in a direct encounter, the great white shark could potentially escape from the megalodon by outswimming it.
Speed Advantage: Great white shark
Megalodon vs. Great White: Bite Force and Teeth
The great white shark has a powerful bite force of up to 18,000 Newtons, delivered by about 24–26 large front teeth, with several rows of replacement teeth behind.

Although a great white shark has one of the most powerful bite forces in the world today, it is nothing compared to the bite force of the extinct megalodon.

The ancient megalodon possessed one of the most powerful bites in history, estimated at 108,000–182,000 Newtons, which is up to 10 times stronger than the bite of a great white shark. Its massive, 7-inch serrated teeth and bite force, estimated at up to 40,000 PSI, could crush whale bones
Bite Force Advantage: Megalodon
Megalodon vs. Great White: Defenses
The great white’s primary physical defenses are its speed and its size compared to other ocean predators. Similarly, the megalodon’s immense size was enough to deter most potential threats, but it lacked the speed of the great white.
Defensive Advantage: Great white shark

The great white shark is fast and has a powerful bite.

Megalodon vs. Great White: Offenses
The megalodon had immense offensive capabilities, with jaws measuring six feet wide. Its teeth were large, and its bite power was immense at 180,000 Newtons. To top it off, it could move at 11 mph, which isfaster than many fish.
The great white shark is a potent creature in its own right, with a bite force of up to 18,000 Newtons and long teeth to puncture their prey’s flesh. However, pitted against megalodon, the great white shark doesn’t stand a chance.
Offensive Advantage: Megalodon
Megalodon vs. Great White: Predatory Behaviors
The megalodon and the great white shark had/has extraordinarily similar predatory behaviors. Their senses help(ed) them find and sneak up on prey or find it along the bottom of the ocean.
Predatory Advantage: Tie
Who Would Win in a Fight Between Megalodon and Great White?

A megalodon would win in a fight against a great white shark due to its overwhelming size and deadly bite force. Both creatures rely on stealth to land the first bite, but it is highly unlikely that a great white could surprise a megalodon, given their comparable sensory abilities. In such a fight, the faster great white might manage a few exploratory bites, possibly causing some damage to the larger, slower megalodon. However, the fight would end the moment the megalodon thrashes around and lands a bite anywhere on the great white.
With such devastating force, anything caught in the megalodon’s jaws would not escape. An entire great white could fit inside the megalodon’s mouth, leaving the great white with no real chance of victory.
Final Advantage: Megalodon
