What do people think of Megalodon sharks? Do they still exist?

There was that incident a few years ago where a 9 foot White Shark had been tagged; and when the scientists who tagged it were analysing the data, they found out that the shark had been chased by another predator and eaten whole. They came to this conclusion because of the instant change of body temperature.
Some seem to think it is an extremely large White Shark in the region of 25 + foot; while some speculate it was something else. The Megladon was mentioned.

I actually think it was a massive White. I have seen an 18 footer up close when I was in SA. It was truly amazing to see such a creature. The thought of them being bigger is amazing. I mean, I cannot describe just how incredible they are.

 

{Ed033's Note - It's likely that this White Shark was eaten by 1 or several killer whales. Killer whales can hunt in packs.

Who knows what exists or still exists in the deep! We apparently know more about space.

I agree with you Bun. Who knows what lurks down there.

BTW Ed: I believe they dismissed Killer Whales because of the depth the Shark was killed at and the body temperature of the predator that killed the Shark was different to a Killer Whale.

 

{Ed001's Note - seems unlikely they would know that, considering Sperm Whales hunt at the deeper depths and the only known predator of the Great White is the Killer Whale. There are Orca pods which specialise in hunting and eating sharks, in particular Great Whites.}

Not sure Ed. I am not that informed about Killer Whales and their attack patterns; or the depths in which they attack. I am just quoting what the scientists said.

 

{Ed001's Note - most scientists know little about them either mate, it is only recently they even realised that pods of Orca hunt Great Whites. Scientists also claimed they were no danger to humans, even though abalone divers in US would tell tales of how dangerous they are. When the divers for the D-Day landings were sent to the States to train in clearing mines prior to the attack, the local divers would tell them that they were to immediately get out of the water if Orca were spotted but they said Great Whites were unlikely to attack. Scientists always used to dismiss that as fanciful tales, but now it is known Orca are extremely dangerous under certain conditions.}

I watched a good documentary about them once, which showed these Killer Whales toying with a seal before they killed it. I felt for the poor old seal.

 

{Ed001's Note - they are incredibly intelligent as well.}

I've heard that line many a time grow bun, and I have to say its ridiculous. While the study of space certainly garners more eyes and financial backing than that of the ocean, what is becoming apparent is that the universe is expanding at a faster pace every day. Leading to the widely acknowledged theory of it being infinite. The ocean may be deep, but infitinitely deep I think not. Not to mention we know of a massive amount of species that live in the ocean, and a even more massive number of sub species etc. We know of different vegetation, micro organisms, breeding patterns and we can even show where land masses were once covered by sea, and ones that now are that once weren't. In contrast, people still debate whether we have even landed on the moon. While some or most on this page believe in alien life outside of our planet, I'm yet to see it proven. So using logic you'd have to say we know a bucket load more about the ocean than we do about space.

I don't know if you've been tracking the story of seaworld and another place whose name escapes me, in the US, Ed001, and the mistreatment of Orcas. Its incredible how poorly these animals have been treated, for a prolonged time, when the evidence shows how incredibly smart and social they are. Even going as far as having a complex language and as you say, the ability to using pack hunting techniques to not only kill Great Whites, but some pretty sizable whales. Easily one of the most fansciniting creatures on earth. The way they heard seals into the shallows and attack them right at the shorelines is insane.

 

{Ed001's Note - I have read a bit of it, though I am personally very much a shark lover, so don't like Orcas as they hunt them. Sharks fascinate me. I did read a few bits about it, it is amazing they were able to get away with it and no one challenged the practices. I found it difficult to have sympathy for the staff that were attacked as those animals are being disgracefully treated. I find it astonishing Sea World was not shut down.}

I think I have seen the documentary about the tagged great white and from memory I believe it was off Australia just north of the GBR and I'm sure there was a slipstream of water that was warmer and had a higer salt content!

But they eventually come to the conclusion it was an orca or orcas! Some of the chunks out of sperm whales is always quite interesting! I have no doubt that there are things large things that we have no knowledge about under the ocean. Just remember the crazy pressure down there! True vertical depth X weight of the water in PPG X 0.052 will tell you there pressure of said depth
