Named for an aboriginal deity sometimes called the Rainbow Serpent, the Wonambi was a massive snake that lived in Australia during the Pleistocene. Measuring as long as 20ft, the two species within the genus were formidable predators in their time.

Now keep in mind that Wonambi were not venomous. Though unrelated to our modern boas and pythons, the Wonambi ambushed and constricted its prey in much the same way. They used their powerful muscles to tighten around and strangle victims.

Wonambi went extinct around 40,000 years ago, and fossils have been found in Southern Australia. It is believed that aboriginal activities may have led to the decline of the large snake.

Status : Extinct for 40,000 years
Location : Australia
Size : Length up to 20ft (6m)
Classification : Phylum : Chordata -- Class : Sauropsida -- Order : Squamata
Family : †Madtsoiidae -- Genus : Wonambi


  1. Interesting history. Were they classified as constrictors or something else?

  2. They are their own separate family of snakes, and all of its members are now extinct.

  3. Ironically, the Aboriginals killed off their God-figure into extinction.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS


For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!
