S1, E2: From highland streams to lowland floodplains and from isolated waterholes to brackish estuaries, Australia’s waterways are complex, competitive, and deadly. In this episode, we open the case files of the continent’s most notorious wetland killers, including the venomous tiger snake, the tiny but fatally cunning Portia spider, and the heaviest hitter of them all, the saltwater crocodile. We also enter the battlefields, witnessing dramatic interactions between predators and prey and revealing the weapons each assassin has in its arsenal.
