The brown snake runs away most of the time, perhaps if you are a mouse you could call it a predator!
. Eastern brown snake (Pseudonaja textilis)
Also known as: common brown snake. Found: throughout the eastern half of mainland Australia. Fast-moving, aggressive and known for their bad temper, eastern brown snakes, together with other browns, are responsible for more deaths every year in Australia than any other group of snakes. Not only is their venom ranked as the second most toxic of any land snake in the world (based on tests on mice), they thrive in populated areas, particularly on farms in rural areas with mice. If disturbed, the eastern brown raises its body off the ground, winding into an 'S' shape, mouth gaping open and ready to strike. Its venom causes progressive paralysis and stops the blood from clotting, which may take many doses of antivenom to reverse. Victims may collapse within a few minutes.

Squid could do this.
Yep quite possible
Must be a very large squid
How big a squid to eat a 4 metre shark is a question worth considering
For mine, I think an unknown sea creature, , yeah probably not but.
An aerial photograph revealed a killer whale pulling along what Museum Victoria squid expert Mark Norman described as either the biggest giant squid on record or something he did not know.
well technicaly a great white shark is coldblooded but in fact it does regulate its temperature..it is warmer than the surrounding waters, i will have to fact find what temp they can maintain.
a whale of any sort is not possible due to not surfacing for a week..now there is speculation about megalodon(giant prehistoric shark) still lurking the depths, it was supposed to have died out millions of years ago but a tooth was found within the last hundred years that dated about 10,000 years old..dating method is questioned though. great whites have remained unchanged for millions of years so its plausible that a megalodon can/could of regulated body temp as well.
based on what i can find about the great whites body temp i might go with a bigger great white. i dont believe a squid or octopi can raise their body temp.
edit on 3-11-2013 by vonclod because: (no reason given)
If the tag was external on the shark, is it possible that another creature took only 1 bite at the shark, and doing so, ate the tag with it?
It doesn't have to be something that eat the whole shark.
