>Here, I report active escape of the aquatic beetle Regimbartia attenuata (Coleoptera: Hydrophilidae) from the vents of five frog species via the digestive tract. Although adult beetles were easily eaten by frogs, 90% of swallowed beetles were excreted within 6 h (0.1–6.0 h) after being eaten and, surprisingly, were still alive. When beetle legs were experimentally fixed with wax, all of the treated beetles were killed in the frogs’ digestive system and finally excreted >24 h (38.3–150.3 h) after consumption. Therefore, swallowed beetles likely used their legs to move through the digestive tract toward the frog vent, hastening their escape. This study is the first to document active prey escape from the vent of a predator and to show that prey may promote predator defecation to hasten escape from inside the predator’s body.
