The aquatic beetle Regimbartia attenuata can actively escape from the vent of the frog Pelophylax nigromaculatus via the digestive system. This beetle species may promote frog excretion to facilitate its escape. マメガムシはトノサマガエルに食べられても6分〜3時間半後にお尻の穴(総排出腔)から生きて脱出できる。加えて、脱出するために、カエルの排便を促している可能性がある。 Photo & video credit: Shinji Sugiura References Sugiura S (2020) Active escape of prey from predator vent via the digestive tract.
