I believe that the Meg died off many years ago. At first I thought that this thread was about food chemicals! Wait maybe I'm thinking of MSG. But gettting back to the topic at hand, I don't think that the Meg could last and I doubt that we have the food sources that it would need to surivive today.

That's plain silly, warm blooded whales eat far more food than sharks of the same size.   Cousteau said the surviving sperm whales consume a biomass in marine oganisms each year eviqualent to the entire human race!  It just shows you how much "life" is still in the ocean despite human depredations.

You could probably get an good idea how accurate that is by calculating the known amount of food a killer whale in captivitiy eats daily, scaling it up to the size/weight of a sperm whale, and then multiplying it by the number of sperm whales believed to be inhabiting the oceans.  But it is a well established fact that cold blooded animals require far less food than warm blooded animals of the same size.  This is not to say that a huge shark couldn't eat an amazingly huge meal, but unlike a whale, the shark could go much longer without food.

So what this means is, our oceans could reasonably support a decent sized population of big sharks. And since they don't need air, therefore have no reason to surface, and most likely live way down in the dark, we may never find one.

Nothing to see here.

Some cold blooded animals like sharks have the ability to raise their body temperatures slighlty higher than the surrounding water temperature, but it is nothing like the heat produced by warm blooded animals.  If sharks were true endotherms/warm bloods they would have layers of blubber and/or fur or feathers, to insulate their bodies to retain that heat.  They are only a bit warmer due to a kind of "friction" created by their constantly moving bodies.  I believe any aquarium attendant could confirm that between a "warm" shark and porpoise/whale of the same weight, the mammal must be fed far more because of its much higher metabolic rate.  Sharks also have a very slow rate of digestion as indicated by the famous incident of the remarkably intact human arm regurgitated by an aquarium shark.  If it had been swallowed by an orca,  the flesh would have been gone in a matter of a few hours.

But all of this actually speaks in favor of the existence of the Meg, for those who question it on the grounds of there being "not enough food in the ocean".  I merely question it because the sperm whale is a more intelligent and efficient top order marine predator in the deep ocean, and in most environments there is only one "top" animal and the competitors go extinct.

Also because sharks have no swim bladder a dead shark would never be found since it would never surface or wash up.... its almost enough to stop me from scuba diving but not quite enough

Any momentary triumph you think gained through argument is really a Pyrrhic victory The resentment and ill will you stir up is stronger and lasts longer than any momentary change of opinion. Demonstrate, do not explicate.

Megalodon.

Source

google Megalodon


OMG, there is no proof on meg larger than 14 meters long, and wqe discussed this on crypto forum, sharks only seem more scary, while there is an animal that should be feared much more than shark, sperm whale (sorry about that), cause it is way more powerful than any megalodon ever existed, why people want to talk about meg? largest and most powerful toothed creature ever existed is sperm whale (not including man). As draconic chrinicler pointed out very good, there are people that survived shark attacks, but it is VERY unlikely that a human survives sperm whale attack, if such occurs.

what about food source for meg? ocean now is as abundant with food as it was then.

you mean that the deeper we go, the bigger sharks we may find Silent BOB?

OMG, do you now ANYTHING about endothermy or ecdothermy at all?

I will not explain to you why warm-blooded creatures have to consume WAY more food than cold-blooded.

Paul, you did not even need to post this, someone already explained that info, and also don't be so rude, some people might not know that stuff, you very seldom here people on this forum being rude, so you shouldn't be either

Back on topic:
I do think the Megladon could still be alive, i mean we have explored very little of the ocean and there are probably a 1000 unknown animals in just like one percent of the ocean, though i do think the Meg adapted to it's current situation, for all we know their could be ten species of Megladon each which has adapted to it's own situation and eviornment, thats just my take on whether megs are still alive or not



sorry, saladins follower.

Paulwhale, this is about Meg, not sperm whales...i came to this thread to talk about megs, and I see you post about how spermwhales are more powerful. plz dont do that...


Megalodons could very well be still alive. Thats the great thing about our oceans, mysterious and beautiful. The know just as much and just as little about our oceans as we do the cosmos! Coelecanth is still alive...crocodile, turtle, snakes are still alive! WHY NOT A MEGALODON!
who knows, it might not even be a Megalodon...it could be something much scarier, much more dangerous, and even bigger!

Sorry, dude, won't happen again,

but then we should make a new thread: About mysteries that are NOt known and that we don't have a clue about, like "SOMETHING" we were talking about, but I will be VERY sceptical.

You guys watch too much fantasy movies, whales are largest animals on earth, and species that are now on 3 place was on 2 in 18 century, before spermaceti hunters hunted it nearly to extinction.

Paul, how can you in one post say you wont post in here about whales but yet by the end you are again  hmm.gif huh.gif


You have to learn the difference between a hypothetical thread and one based on facts. Almost everything we know about Megs are theories, we know almost next to nothing about them.
