well having watched the program i found it interesting.
They pretty much ruled out orcas due to the temperature, and giant squid due to the size of the mouth compared to the transmitter. So they concluded
it was probably another very large great white that did the deed. They did film a large great white further up the coast in excess of 5m.
However it did get me thinking it might have been something else.
Megalodon does spring to mind.
Now im not talking about the meg where the estimated size is around the 30m mark .... that size of predator is simply just too big to be sustained
However estimates from some meg teeth put the size at around 16m - still very big i agree.
My thinking is that over the time the size of the Meg slowly reduced due to the reduction in food.
So yes in prehistoric times the meg has probably gigantic ... with a maximum size of around 30m, but what if over time that maximum size dropped to
around 20m with an average of say 10-15m.
Still too large you think?
Well look at the Great White. It was around during the time of the Meg, indeed there are many theories that speculate Meg and The Great White were
very closely related.
Now the maximum size of modern day Great Whites is still up for discussion however from the various reports in the last 100 years I think its safe to
assume there were(are) Great whites around the 7m
So its entirely possible that an average Meg would only be 3m bigger than a large great white ... juvenile megs would be similar to most adult great
whites. So could sightings of large Great whites actually have been a young Meg?
I believe that would be possible.
After all why would the larger of two species of shark go extinct when apparently they were very similar in many ways - the bigger difference was
maximum size (although im pretty certain prehistoric great whites were a lot bigger and have downsized in line with the food source) - why would the
Megs also not downsize according to food source.
Even Megs teeth were apparently very similar to a great whites - except for size.
So why havent we seen a Meg? well maybe we have - as I have already said the theory is that they were similar to great whites, so juvenile and young
adult megs could easily be mistaken for large great whites.
The sticking point however is where are the adult megs .... well remember there are countless stories of massive great whites out there... maybe they
arent great whites but modern day megs.
So will we ever see a 30m Meg - i dont think so
Will we ever see a 10-16m Meg - I think its entirely possible.
When considering the meg this account always springs to mind and sticks with me for some reason
"One of the mostfamed examples of a possible Megalodon sighitng was retold by Australian naturalist David Stead. Though widely circulated, this
account is generally regarded as of little value, because most of the claimants are anonymous: "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. But the lengths they gave were, on the whole, absurd. I mention them, however, as an indication of the state of mind which this unusual giant
had thrown them into. And bear in mind that these were men who were used to the sea and all sorts of weather, and all sorts of sharks as well. One of
the crew said the shark was "three hundred feet [90 m] long at least"! Others said it was as long as the wharf on which we stood – about 115 feet
[35 m]! They affirmed that the water "boiled" over a large space when the fish swam past. They were all familiar with whales, which they had often
seen passing at sea, but this was a vast shark. They had seen its terrible head which was "at least as long as the roof on the wharf shed at Nelson
Bay." Impossible, of course! But these were prosaic and rather stolid men, not given to 'fish stories' nor even to talking about their catches.
Further, they knew that the person they were talking to (myself) had heard all the fish stories years before! One of the things that impressed me was
that they all agreed as to the ghostly whitish colour of the vast fish. The local Fisheries Inspector of the time, Mr Paton, agreed with me that it
must have been something really gigantic to put these experienced men into such a state of fear and panic."
