Clarence River Snake

Tropidechis carinatus

Highly Venomous - Extremely Dangerous

The dangerously venomous Rough-scaled snake can be distinguished from the harmless Keelback by its single anal and subcaudal scales (all divided on the Rough-scaled snake), a straight mouth (slightly up-curved on the Keelback), and the absence of a loreal scale.

If you look at this photo you will notice that there is one large scale in front of the eye (preocular) and in front of that is the nasal scale. However the Keelback would have an extra scale called the loreal scale between those scales.

Note that Keelbacks may have obvious lip markings where the scales meet (sutures) which are normally absent on the Rough-scaled Snake, however this is not a reliable method of differentiating the species.

Note that Rough-scaled snake Tropidechis carinatus patterning varies considerably, and sometimes has more distinctive banding than those pictured on this page. Its distribution overlaps that of the Tiger snake in some regions and it is often mistaken for that species (which is also extremely dangerous).

This is a neonate Rough-scaled snake Tropidechis carinatus, locality unknown.

The Rough-scaled snake Tropidechis carinatus is regularly mistaken for the common Freshwater Snake or Keelback Tropidonophis mairii- (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!

Venomous snakes do not always inject venom when biting, however due to the extremely high toxicity of the venom of this species, it is vital that first aid is performed immediately (constrictive bandage etc) and the patient is taken immediately to hospital. Lack of symptoms may not mean that the victim has not been envenomated.

Correct and immediate treatment for this species and other dangerous snakes increase the chance of survival significantly.

Although people are commonly bitten by dangerous snakes in Australia, the actual number of deaths is actually very low, due to antivenines and medical procedures.

Tiger snake antivenine is normally used to treat Rough-scaled snake bites.

Do not confuse this species with the Rough Scaled Python Morelia carinata
