Insect can escape after being eaten by frog, scientists find

The insect Regimbartia attenuata can escape even after being devoured by certain species of frog, among them Pelophylax nigromaculatus, Japanese ecologist Shinji Sugiura of Kobe University announced on Monday.

Like other kinds of frog, Pelophylax nigromaculatus’ lack of teeth makes it unable to kill the insect before eating it. This is done instead by the digestive tract.
But that mostly doesn’t work with Regimbartia attenuata, which, Sugiura says, stimulates the frog to defecate and, like Tim Robbins’ wrongly imprisoned Andy Dufresne in 1994 film “The Shawshank Redemption,” crawls through a river of excrement to its freedom.
It’s the first time that the flight of prey after consumption has been documented scientifically, according to researchers from the magazine Current Biology.
The aforementioned insect and frog are found in the same paddy fields in Japan. To investigate the insect’s capacity for self-defence, Sugiura fed it to young and adult frogs.
