This story is getting a lot of traction even though it shouldn't. There's a few rational explanations it could be either a orca or a sperm whale, one of them can dive deep enough to explain this. There's also the possibility it was a larger shark given that this shark was nine feet and some great whites can grow up to 26 feet. Also it could be something smaller because the tracker is in the fin so it's possible it fell out or something got a small piece of the shark. The article is sensationalized for attention and it's working. Case closed.
read this and come back to the thread more informed breh, s[erm whales dont eat sharks there jaws are too thin and dont have upper teeth, and orcas cant dive that deep for that long a period... also the temperature of the body indicates it wasnt a mammal, so either a new species of shark, or an undiscovered fish/reptile did this thats why its news
Was a 10 foot Great White eaten by an even bigger shark? Hunt for 30 foot SUPERPREDATOR
- A three-metre great white shark was tagged off the WA coast
- Four months later, the tag washed up with signs it had been eaten
- Data on the tag showed changes in temperature and depth
- A filmmaker has tried to solve the mystery and believes another 'huge' shark was responsible for eating it

A filmmaker and scientists believe a 'huge' super shark could have eaten a three-metre great white shark that was being tracked in a satellite program.
The tracking tag washed up on a Western Australia beach with signs it had been bleached by stomach acid and its data showed rapid changes in depth and a rise in temperature reflecting the animal that ate it.
Filmmaker Dave Riggs was part of the crew documenting the Commonwealth Scientific and Industrial Research Organisation's white shark satellite tagging program in 2004 when the three-metre animal was identified about four months before the tag washed up in the Bremer Bay area.

'There was no algae growth and it (the tag) was white - it looked like it had been bleached in stomach acid,' he told MailOnline.
The tag showed an abrupt 580-metre-deep fall down a continental shelf and huge temperature rise, indicating the shark had become prey to a much larger creature.

'The data contained on the shark showed at least the tag had been ingested with an animal with the internal temperature of 26 degrees,' Mr Riggs said.
After talking to sperm whale hunters in the Bremer Bay area, Mr Riggs learnt of sightings off of an animal about 10-and-a-half metres long and others that were tracked travelling at up to 4.5 knots but did not surface.

Filmmaker David Riggs has been trying to solve the mystery of what killed the shark
Through crowd funding, Mr Riggs has been completing expeditions to an area 60 kilometres off the Bremer Bay coast where the shark was tagged.
He has invited scientists to go with him and said none had discounted his theories.
Mr Riggs believes it is most likely that the shark was eaten by another large shark of the mackerel species. 'But by the same token, I'm not 100 per cent convinced,' he added.
'Looking at the profile of the animal that ate it, 26 degrees, that's pretty high but not enough to be a mammal but it's something seriously huge to sustain that temperature - the larger the animal, the more capable it is of an elevated temperature,' he said.
Mr Riggs added that based on the tag data, the animal that ate the device had a stomach area at least one-metre wide.

Mr Riggs believes another massive shark could have eaten the three-metre animal

There have been reports of a 10-and-a-half metre animal in waters near where the shark vanished
