摘要

蛇和龟之间的相互作用很少被记录在案。我们在西虎蛇(Notechis scutatus occidentalis)胃内容物中记录了一只小切洛地那(Chelodina oblonga)。这是西澳大利亚州首次记录到蛇和新生淡水龟之间的相互作用。实地触诊未能发现海龟幼龟,这表明如果没有解剖,海龟幼龟被蛇捕食的概率可能比通常报道的要高。蛇捕食幼龟可能会给澳大利亚濒临灭绝的淡水龟种群带来额外的压力,这需要进一步的调查。

First record of predation of a hatchling turtle by the Western tiger snake (Notechis scutatus occidentalis).
Snake-Turtle interactions have been rarely documented. We recorded a hatchling Chelodina oblonga within the stomach contents of a Western tiger snake (Notechis scutatus occidentalis). This is the first recorded observation of an interaction between snakes and hatchling freshwater turtles in Western Australia. Field based palpation failed to detect the hatchling, suggesting that without dissection, turtle hatchling predation by snakes more generally could be higher than commonly reported. Snake predation of hatchlings could be placing additional pressure on threatened populations of freshwater turtles in Australia, warranting further investigation.
