Yeah, but what about the Octopus? It gets pulled in, then it casually walks out leaving behind silence. So did he go all medieval on the worm and take it out? Pay it off? Squirt ink in his mouth to make him go ewwwww? I hate cliff hanger endings.
I was wondering that too, and hoping the article would explain.
My assumption is that the Octopus' body yields enough to sustain quite a bit less damage, and the bobbit worm releases it's prey while under ground to get a better grip.
Alternatively, maybe the Octopus released ink while under the soil and it confused/irritated the worm.
If it had released a significant amount of ink, I would have expected to see it come back up in the water with the octopus. Another possibility is that the octopus was venomous and bit the worm.
I'm guessing the octopus released ink at the very least. Moreover, octopi are renowned for being able to squeeze through very small holes and doing so quickly, so maybe it found a quick route out of the worm's mouth at a fortuitous moment.
