Now, thanks to some novel camera work, that technique has been documented in astudypublished today inCurrent Biology.
One camera captured conventional video, while another used x-rays to see what was happening in the fishs guts.
Rather than give into fate, the eel got busy.

In footage released alongside the study, the fish can be seen lying placidly at the tubs bottom.
Inside it, however, the eel was battling valiantly.
One eel could be seen circling through the stomach, as if looking for an exit.
It used its tail to probe through the fishs stomach, eventually sliding it up into the esophagus.
Eventually, the tail was used to push through a gill.
The experiment was repeated 32 times, and only four eels didnt attempt an escape.
It was a quick process, too, with the average escaper taking only 56 seconds to liberate themselves.
