What Is a White-Crowned Snake?

Cacophis Harriette more commonly known as the White-crowned snake is a small venomous snake native to Australia more specifically New South Wales, Queensland.

Queensland is unique in the sense its home to a whopping 120 different species of snake and around 65-70 percent of these are venomous.

It gets its name from the white band of scales present on its head which looks similar to a crown. White-crowned snakes spend their days hiding under leaves and other ground debris, but come night emerge looking for food. They prefer damp places, so be alert for them under logs, rocks, and sometimes even compost bins. They are not aggressive by nature and usually look to avoid conflict with bigger animals such as dogs, cats, or humans. They are usually around 40cm in length growing up to around 56cm max.
