10 ft. white shark being eaten? Mystery solved!

Yesterday we talked about the international headlines of "Great white shark being eaten by sea monster".

Here is a response by CISRO, the organization who placed the tag on the shark in question.

When we looked at its data there was a period of approximately three weeks just before the tag surfaced where the temperature recorded was higher than the surrounding sea, but where the tag continued to ‘dive’ in a pattern consistent with a white shark. During this time, the tag failed to record light. Data before and after suggest the tag was functioning normally. The temperature recorded for these three weeks was consistent with that of the core body temperature of a white shark but too low for something like a killer whale.

They go on to explain, what they think had happened.

At one point the shark that had eaten the tag dived to a depth of 570 m – this is not unusual for white sharks – it is normal behaviour. This dive took place about one week prior to the tag recording the higher temperatures (not immediately before as some have reported) and the two events are not related.

All evidence suggests that the tag had been eaten by another white shark. We have seen white sharks biting each other before, sometimes removing pieces of tissue in the process. We concluded that this was the most likely explanation – One shark bit off a little more than he could chew and ended up swallowing the tag. 

We never concluded that the 3m shark was consumed by another much larger shark.

Yesterday I questioned the "scientists" conclusion, that a sea monster ate the shark. Now we know that there were not even any scientists that concluded that, it was simply the filmmaker ignoring what the group who placed the tag in the first place had to say. Now that's something you'd expect from a Sci Fi channel production, not a Smithsonian "documentary"!
