So snakes are cold blooded but they can live in africa

Several species of snakes have demonstrated the ability to survive in very hot regions including deserts. They are ectothermic animals and can burry themselves in the sand during the day time in such hot regions to avoid the immense heat. So it is not a matter of surprise for us, if they can be found in Africa.

and by the way don't you think after a million years the climate could change so that currently warm water regions were once cold areas and like I said , a snake is cold blooded, but they live in africa right?

The world of Megalodon was very different from the one in which we thrive.

The climatic conditions and the oceans were noticeably warmer during the Miocene epoch, then they are today. The Ice Ages of Pliocene and Pliestocene periods have immensly changed the geological and climatic conditions of the world and the oceans have cooled down a lot as the result and many warm water regions have vanished.

Hence, Megalodon thrived in the warm waters around the world.

However I would like to point out that all marine animals have certain limits of tolerance for temperatures. The Warm blooded or endothermic creatures have greater tolerance limits of temperatures than the Cold blooded or poikilothermic creatures. The endothermic creatures can adjust within the major changes in the temperatures with much better efficiency. However some very large fish can be gigantothermic and can exhibit greater level of tolerance of temperatures than the pure poikilothermic fish.

Megalodon might have been able to tolerate the cold waters but within specific limits. It was not able to tolerate the water temperature in polar regions however at the end of pliocene epoch.

And I did not say that Megaladons and Great whites arent close relatives, read Capeo's earlier post quoting me and he said that Megaladons and Great whites arent currently thought to be related

Capeo's view point is very formal in nature. In the old times, it was believed that the Megalodon was the direct prehistoric ancestor of the Great White Shark, but this was proven to be not true in the later years.

Though Great White Shark and Megalodon are still distant cousins in the bigger picture. The anatomical similarities between these two sharks cannot be ignored, so for this reason the Great White Shark is termed as the closest living relative of Megalodon.

And by the way, don't you think that Megaladons cant be like snakes , eat a BIG nice meal of fatty animal and stay dormant for almost a week that would cut down on the energy output you know.

Megalodon had massive metabolic requirements. To sustain its immense size, it had to eat a lot. Such a creature may not be able to stay dormant for an entire week without eating any food.

in fact, i dont know if any sharks are deep sea predators.

Some sharks are deep sea predators or can hunt in deep waters. Pacific Sleeper Shark is one such example.

its possible for it to still live because we have found a few animals of its size. And for all those saying that the big animals where known for 100s of years before being fully reconized by the world ill say the there are stories of 50 to 100 foot sharks dateing back to about since people made the first boat lol such as the ledgend of the giant shark that guards the island of hawaii(megamouth shark). There is always the posabilty of them living because u can never prove the negative in anything. also those saying it was a shallow water shark ill say the we hav only ever found coelacanth fossils in the shallow inland seas but the live ones are in deep waters things have a way of changeing over a few million years i think its a theory of something tongue.gif . Ive personaly thought alot about it and it would be posable for it to get the food it needs ill put my thoughts into the diffrent habatits.
deep water: with a small amount of body mass groth with a layer of blubber like fat (greenland sharks have it proveing that sharks can have it) it could handle the cold and with the size of its "bones" it could theoreticly live down there. as for its food needs gaint squid has alot of callories. proof of that is sperm whales make trips just to get them and that takes us to that sperm whales have tons of fat to keep them warm in the deep water so there is plenty of food down there.
mid region: pritty much the same but with less fat and no giant squid but lots of whales thumbsup.gif.
diveing: this is the most likly one they could dive deeper to get squid while eating whales and such closer to the surface
as u can see its possible and since 9 times out of 10 a shark body sinks/is neutraly boyant when it dies we would probably never get a body in time for it to be anything but a globster and since 99% of the time its not identified it could be undiscoverd for a very long time and then theres scavangers so the chance of it being found is less then 1% of the 40% chance it could be alive at all
p.s. i talk way to much about this lol but i spent about 3 years doing reserch on this at every posable angle so u can all forgive me right grin2.gif


most of the large species found have never been CLAIMED to exist. we just found them by sheer chance. a megaladon would die out quickly today, due to the tiny amount of food in todays seas compared to the sea 70 million yrs ago.

Makaya is very right, there's far too little food.

Giant squids and whales would be good food

Also I searched some sites, and no, megaladons are not mega sharks, only about 50 feet, smaller than some whales, also, sharks have been known to live at 13000 feet down

megaladons ranged from 50-60 feet max. and its doubtful that squid would be enough since squid are rarely seen down there. sharks do not swim that deep, and if they do, they are small

Unfortunately! Most of the sites contain out-dated information about Megalodon. And very few sites contain updated information regarding this animal.

Megalodon is currently recognized as the biggest known carnivorous fish to have ever existed.

To be honest! We would never know that how big this shark could really grow.

But some fossilized remains indicate that this creature could reach 61 feet in length and this estimation is based on a conservative size measuring technique. Some say that it could actually grow bigger.

Now very few species of whales can attain or exceed this size.

Hence, it was a Mega Shark in every sense and could take on any creature that moved in water.

Check "The Perfect Shark" video in my sig for a good idea.

i wasnt really saying that they live im saying that they could hav i did alo t of research and i found it to be a 40% chance at most with my lower one being 33% and since all laws of sience say u cant prove the negative there is always the chance and if it ate a lot and i mean a lot of squid and whales it could still live. i personaly after my research think that if we find one it will have something to do with hell and ice wink2.gif but we cant discount that one can be out there........maybe.......but probly not.........but it may..........or it may not........ tongue.gif. If u look at what i said from this way ull see im only saying how it could hav if it did. Not how it did and even if it did make it here theres only a 0.4% to a 0.33% chance we will ever find it but theres still a chance even if its a 0.00000000000000000000000000000000000000000000000000000000000001% we still could find it.

Probability doesn't mean anything here. It either exists or it doesn't.

No law says that a negative can not be proven. I can prove that 1 doesn't equal 2. I can prove that E doesn't equal MC3

so i guess we better tell the sperm whale it can't hunt krakon any more.

probability has every thing to do with this stuff if i said i saw a cat with 900 legs then every1 would laugh outright but if i said 6 people would ask if i had proof first i think disgust.gif that may be the one great problem with crypto sites no one looks at the chances of it existing....and u cant prove a negative. it means there is no way u can prove that something cant happen/exist(not counting math which u are doing since true math is a balance and is provable) such as the sun riseing in the west tomorrow if somehow the world reversed during the night it would now that probaly wont happen but it may......but thats waayyy off topic i am just responding to the fact that people always seem to attack people that bring meg and liveing dinos up i personaly dont beleave that they still exist but to try and prove not is impossable and it bugs me to no end to see people just call the person stupid for thinking they might some people on here dont and try and make them understand the facts but a lot dont and just say they cant without looking at it from the what if side i always try and follow the logic of the person posting before i post my reply and this guys logic was very close to my own theories of what if. I never really said i support eather way i just said how it could have.

I believe its a possibility but not strongly i think that as big as they were and how much they ate that they would be gone cause of overfishing by man today

not really. as much as i suggest a sasquatch, which is 7-8 feet could exist in the remote, uninhabited forests, its hard to believe that 60 foot sharks are alive without even a sighting to lend it credence.

50 feet as an average not the biggest, because somebody posted that the mega is bigger than a whale ... not that big maybe . Blue whales are huge arnt they . yeah only about 4 species can attain that size

What do you mean Giant squids are rarely seen at 13000 feet, only like 5 to 10 trips have been made that far down, and sperm whales eat squid too and they have enough nutrition to swim and live and fo whale stuff

50 to 60 foot sharks still alive?Pure hogwash.

yeah their probably are sightings of 20 to 25 ft sharks, not 50 or 60 ft sharks!

they can't even agree when the megalodon went extenct.


any where from 1 million years ago to 10,000 years ago. wiki

[edit] Supposed megalodon sightings
Some relatively recent reports of large shark-like creatures have been interpreted as surviving C. megalodon, but such reports are usually considered misidentification of basking sharks, whale sharks or submarines.

One well-known example was reported by writer David G. Stead in his book about sharks that was released in 1963. The brief excerpt of this account is mentioned below.

“ In the year 1918 I recorded the sensation that had been caused among the "outside" crayfish men at Port Stephens, when, for several days, they refused to go to sea to their regular fishing grounds in the vicinity of Broughton Island. The men had been at work on the fishing grounds---which lie in deep water---when an immense shark of almost unbelievable proportions put in an appearance, lifting pot after pot containing many crayfishes, and taking, as the men said, "pots, mooring lines and all". These crayfish pots, it should be mentioned, were about 3 feet 6 inches [1.06 m] in diameter and frequently contained from two to three dozen good-sized crayfish each weighing several pounds. The men were all unanimous that this shark was something the like of which they had never dreamed of. In company with the local Fisheries Inspector I questioned many of the men very closely and they all agreed as to the gigantic stature of the beast. ”
danielost
C. megalodon teeth have been discovered that some argue date as recently as 10,000 to 15,000 years ago. This claim is based on the discovery of two teeth by the HMS Challenger scientific expedition (these teeth were dated by estimating the amount of time it took for manganese to accumulate on them, although it is quite possible the teeth were fossilized before being encrusted). Problems with this dating method include the simple fact that deposition of manganese oxide on the seafloor is not constant, and can only serve as a minimum age. In all likelihood, these teeth are probably much older.
