A Megalodon population couldn't survivre today PRIMARILY because of the reason of why it vanished : there is not enough food source for these kind of giants macropredators today.


The Orca species wouldn't be a major threat, since Orcas RARELY prey on large baleen whales, and we have no clear records of Orcas preying on large, powerful isolated Bull Sperm Whales.

Orcas would target the very juvenile C.megalodon and I assume would rarely engage a +7 m individual and never a +12 m one.

Human would be the major threat of course, though challenging C.megalodon would be without comparison with challenging other large animals Human have encountered in their history.

Megalodon would have vanished because of Human ? No, it would have vanished much more previously because of the modern marine life structure.

However, if C.megalodon would have survived until today, I am sure that human world colonisation using oceans travel would have been different and more or less delayed.

I'm not totally agree with you,the overfishing of shark are a serious problem for the shark population,overall the destruction of ecosystems,pollution,overfishing are in a great part responsible of the the extinction of many species,we can't deny that we are responsible in major part of all the problems of ocean's ecosystems,and of course this must change!I do not underestimate the impact of our society on nature because it will be like give credit to the people who destroy the biodiversity.

I was not talking about today but during human history.

C.megalodon could have been a relatively big hazard for old vessels.

As for today, we do not need all the population, over-fishing and other effects of our species in the oceans for destroy C.megalodon, the simple actual marine environment are not made for this kind of giant macro-predators, or any other. One individual could survive, not a population.

I had voluntarily left side the problem that megalodon posed to the ecosystem.
to discuss about our impact(or rather the impact of our crap species)on it life,and take the opportunity to say that we transform our planet into hell for every animal(us include) ;)

Outcompeting, climate change, or because whales began to move into colder waters. Megalodon couldn't follow and eventually starved to extinction.

The idea that Meg was outcompeted is a minority view. The majority of scientists believe that climate change, followed closely by whales adaption to very cold waters, led to its extinction.

I don't think Megalodon could survive very long today. Competition/predation would not likely be a problem for a healthy Megalodon population. Megalodon and orca pods would probably practice mutual avoidance with occasional predation of Megalodon on solo orcas or pod predation on young juvenile Megs under 7-8 meters. Great whites and other sharks would avoid Megalodon like the plague.

But the main problems facing Megalodon would be the drastically reduced whale populations and human predation. Megalodon was a cosmopolitan species, but its range and prey sources would be limited by the colder waters today, and it would be hunted mercilessly by man, just like every other large marine animal. A Meg population would die out rather quickly in today's world.

From "Megalodon - Hunting the Hunter", the various theories of extinction provided given to Renz, by experts giving their professional opinion:

Vastly minor theory suffering big incoherence, not even hinted in the most recents papers or serious informations about C.megalodon.

One Megalodon individual living today : it would have no problem and would probably sighted by humans.

One population wouldn't survive, justly for the main probable reasons the species may have vanished.

one megalodon would probably be protected and studied by scientist.
a population have no chance to survive for the previous reasons and for the degradation of the marine ecosystem.

5 different theories actually compiled by Renz in consultation with experts, none of which have been refuted.

No one has been followed in recents informations and documentations.
Not even when you consult privately renamed paleontologists.
