It's the first time scientists have observed prey behavior inside a predator's digestive tract.

A species of Japanese eel has proven to be a master escape artist, capable of wriggling its way through a predator’s digestive tract to freedom.

While it was known previously that Anguila japonica (which, despite its name, can be found off the coasts of Korea, Taiwan, China, Vietnam, and the Philippines, as well as Japan) was capable of escaping from its predators’ insides, it wasn’t clear how they pulled it off.

Now, thanks to some novel camera work, that technique has been documented in a study published today in Current Biology. According to the team, it’s the first time the behavior of prey has been captured while it’s still inside a predator’s digestive system.
