Tiger snakes (Notechis scutatus) are highly venomous snakes found across southern Australia and several nearby islands, often associated with wetlands and other water-rich habitats where their frog prey is abundant.
Not always striped
Many tiger snakes have dark banding that gives them their name, but the resemblance to an actual tiger's stripes is loose at best — and some populations, particularly on certain islands, look quite different from the "classic" banded pattern. The variation between populations is significant enough that coloration alone isn't a reliable way to identify a tiger snake.
A wetland hunter
Tiger snakes are strongly associated with swamps, creeks, and other watery habitats, where frogs make up a large part of their diet alongside small mammals, birds, and reptiles.
