[1] Forest rain frogs can range in colour from red, orange, yellow, green, and purple.

The purple frogs are known to contain a defence mechanism consisting of a toxic chemical on their slimy exterior.

If contact is made with this toxin the temporary effect of paralysis can occur.

[citation needed] Breviceps sylvestris taeniatus is a subspecies of the forest rain frog and is found near Soutpansberg.

It is separated from the main species by uninhabitable terrain.
