A hitherto unknown feeding mode among snakes is described for the colubrid snake Oligodon fasciolatus in Northeast Thailand. Three cases of O. fasciolatus using enlarged posterior maxillary teeth to cut open the abdomen of a live poisonous toad Duttaphrynus melanostictus and eat its organs are described. The snakes and toads fought vigorously, and the toads secreted toxic white liquid on the dorsum and neck. The snakes inserted their heads into the abdomen of the toads, pulled out some of the organs and swallowed them. The snakes and toads were adults. All three cases were documented by extensive photographic material. In a fourth case from Central Thailand, an adult O. fasciolatus was observed swallowing an entire semi-adult D. melanostictus. The majority of all snake species swallow their prey in one piece, but to place our observations in a broader context we review a number of exceptions.

剔骨活着：在泰国的食蟹（Oligodon fasciolatus（Günther，1864））进食食管Duttaphrynus melanostictus（Schneider，1799）的新颖而惊人的喂养策略

描述了泰国东北部的蛇形蛇Oligodon fasciolatus的蛇迄今未知的进食方式。描述了3例使用上颌后牙扩大的切开活的有毒蟾蜍Duttaphrynus melanostictus的腹部并进食其器官的Fasciolatus病例。蛇和蟾蜍奋战，蟾蜍在背部和脖子上分泌有毒的白色液体。蛇将头插入蟾蜍的腹部，拔出一些器官并吞下它们。蛇和蟾蜍是成年的。这三起案件均由大量摄影材料记录下来。在泰国中部的第四例病例中，观察到一个成年的O. fasciolatus吞咽了整个半成年的D. melanostictus。所有蛇种中的大多数都将它们的猎物吞噬成碎片，
