The Rough-scaled Snake (Tropidechis carinatus) is regularly mistaken for the common Freshwater Snake or Australian Keelback (Tropidonophis mairii) which is a harmless colubrid, and grows to about 1 metre long. Females gives birth to an average of about 10 live young (possibly every second year). It is generally regarded as an aggressive species. Although those I have encountered in the wild have shown no sign of aggression at all!
