7. Black tiger snake (Notechis ater niger)
LD50: 0.131
The black tiger snake inhabits southwestern Australia, Tasmania, and islands off western Australian coasts. It is a subspecies of tiger snake but they are fairly distinct species, and inhabit a bit drier habitats than common tiger snakes. They also differ in color, being almost wholly black on the dorsal (back side) and usually slightly lighter on the ventral side (belly).
