What killed the Megalodon?
Competition from other predators of marine mammals, such as macropredatory sperm whales which appeared in the Miocene, and killer whales and great white sharks in the Pliocene, may have also contributed to the decline and extinction of megalodon.
What animal could kill a Megalodon?
There are many animals that could beat megalodon. Some say megalodon ate Livyatan but it was an ambush predator and Livyatan might have eaten it too. The modern sperm whale, fin whale, blue whale, Sei whale, Triassic kraken, pliosaurus and colossal squid could all beat the megalodon.
Could the Megalodon still exist?
But could megalodon still exist? ‘No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. The sharks would leave telltale bite marks on other large marine animals, and their huge teeth would continue littering the ocean floors in their tens of thousands.
What hunted Megalodon?
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and …
Can a orca kill a Megalodon?
A pod of carnivorous whales, orca size (20–30 feet) or larger, could kill a megalodon. They include the 20 foot Aulophyseter, Zygophyseter and Brygmophyseter (a large enough pod would be dangerous prey for the megalodon) the 45–60 foot Livyatan, and the 50–70 foot Sperm Whale itself.
Can a mosasaurus kill a Megalodon?
While a similar length, the Megalodon had a much more robust body and huge jaws built for devouring whales and other large marine mammals. A Mosasaurus would not have been able to get its jaws around the much thicker body of the Megalodon. It would just take one catastrophic bite for the Megalodon to end the battle.
Could a Megalodon kill a blue whale?
Megalodon was potentially capable of taking on Blue Whales, but it is doubtful they’d go for something so large and tedious to kill, especially something 40 feet longer and far heavier, sort of like a lion going after an elephant. Besides, there was probably far better, far smaller whales to eat.
What’s bigger blue whale or Megalodon?
When it comes to size, the blue whale dwarfs even the largest megalodon estimates. It’s believed blue whales can reach a maximum length of 110 feet (34 meters) and weigh up to 200 tons (400,000 pounds!).
Who would win a megalodon or a blue whale?
A blue whale can be over three times more massive than even the largest Megalodon and maybe 5 or more times more massive than an average one. Even a small blue whale would be twice the mass of a small Meg.

Orcas are apex predators, at the top of the food chain. No animals hunt orcas (except for humans). Killer whales feed on many different types of prey, including fish, seals, sea birds and squid.
Why do killer whales not attack humans?
There are a few theories about why orcas don’t attack humans in the wild, but they generally come down to the idea that orcas are fussy eaters and only tend to sample what their mothers teach them is safe. Since humans would never have qualified as a reliable food source, our species was never sampled.
Can a orca kill a shark?
It turns out that great white sharks aren’t always the hunter — the feared killers of the ocean are prey for orcas. There have been reports of killer whales attacking several species of sharks off the South African coast since 2017 and the deaths were eventually linked to two killer whales in the area.
Who would win between a great white shark and a killer whale?
Both the great white shark and the killer whale or orca are fearsome top predators. But of the two massive animals, the killer whale may be the more formidable one, a new study has found.
