The Venomous Western Brown Snake

The western brown snake or gwardar, is a species of very fast and highly venomous elapid snake native to western Australia. The name gwardar means “go the long way around” in Aboriginal language. Presumably, this name is a wise advisory to keep clear of this snake. Western brown snakes inhabit arid and semi-arid areas, dry forests, grasslands, wooded savannas, and scrublands.

First the Stats…

Scientific name: Pseudonaja nuchalis
Weight: 7 – 9 lbs
Length: Up to 6 feet
Lifespan: 7 – 10 years

Now on to the Facts!

1.) These snakes are able to lighten or darken their color based on the needs to stay cooler or attempt to warm themselves. Lighter coloration will reflect heat and darker will absorb it.

2.) The western brown snake is diurnal (active during the day).

3.) Western browns primary prey are rodents, frogs, lizards, birds, snakes, and even eggs.

4.) They tend to hide in abandoned underground burrows, large cracks in the soil, between rocks, and fallen timber.

5.) When cornered, these snakes will raise their heads above the ground and form an “S” shape with their elevated body and open their mouths to a gape, hissing. These snakes can be very aggressive if threatened, but typically tend to scurry rather than stay and fight.

But wait, there’s more on the western brown snake!

6.) The main predators of the western browns are mulga snakes and large birds of prey.

7.) Due to their short fangs, a bite is not always felt. Its venom contains neurotoxins, nephrotoxins, and a procoagulant, although humans are not usually affected by the neurotoxins.

Did you know…?
Human symptoms of a western brown snake bite are headache, nausea/vomiting, abdominal pain, severe coagulopathy (blood clotting), and sometimes kidney damage. Paralysis can also occur in cats and dogs.

8.) Mating season takes place from spring – mid-summer. Males fight by entangling their bodies and swinging their heads at each other; as well as biting each other to establish dominance.

9.) Females lay between 12 – 38 eggs, 6 – 9 weeks after copulation. Eggs hatch after 60 – 80 days.

10.) More males are produced than females, regardless of incubation temperature.

Critter Man

With over 40 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge.I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or air.I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!Let it be said that I have been oft times accused of loving animals more than I love people. I can neither confirm nor deny this.
