**Nagasaki, Japan** – A new study published in Current Biology reveals the remarkable escape artistry of the Japanese eel, *Anguila japonica*. Researchers at Nagasaki University have captured on camera the eel’s ability to wriggle its way out of a predator’s digestive tract, providing the first visual evidence of this incredible behavior.

Using a combination of conventional and x-ray cameras, scientists observed eels being swallowed by predatory fish. Rather than succumb to their fate, the eels were observed actively navigating through the predator’s stomach, utilizing their tails to probe for an exit. Remarkably, the eels were seen traveling upwards through the esophagus and finally out the predator’s gills.

The study, which involved 32 trials, demonstrated the eels’ tenacity and efficiency in their escape. While not all eels attempted to escape, a significant number (13) managed to get their tails out of the gills, with 9 fully escaping. The average escape time was only 56 seconds.

“The most surprising moment was observing the eels escaping by going back up the digestive tract toward the gill,” said researcher Yuuki Kawabata. “We expected them to escape directly from the mouth, but witnessing their desperate escape from the stomach to the gills was astonishing.”

This discovery adds to the growing body of research on the remarkable survival strategies employed by various species. Previous studies have documented similar feats of escape artistry, such as parasitic worms forcing their way out of predators and beetles turning themselves into living laxatives to escape.

The Japanese eel’s escape technique highlights the ingenuity of nature and its ability to adapt to even the most challenging situations.
