The Darwin region of the Northern Territory is home to over 40 native snake species.
These snakes can range from the perfectly harmless to the virtually deadly.
Continue reading for more information about the main identifying characteristics and preferred habitats of seven of Darwin's most common snake species.
Only by increasing your awareness of snakes can you decrease your risk of a snake bite.
We also cover snake bites in our general and childcare first aid courses - head to our website to find and enrol at a training location near you, including Darwin!
Golden tree snake
- Can grow up to 2 metres long
- The scales on its back and sides can range from gold to yellow brown, occasionally with lighter markings - the scales on its underbelly are also lighter
- The scales on its head and neck can range from slate grey to bluish
Golden tree snakes are frog eaters and so thrive in urban areas where there are plenty of green tree frogs, as well as trees and hollows in which they can shelter.
Though they are not venomous, they can emit a foul odour if handled firmly.
Olive python
- Can grow up to 6.5m long
- The scales on their back and sides are shiny and can range from olive to yellow brown
- The scales on their underbelly can range from cream to yellow
- They have a large, oval shaped head
These non-venomous, ground-dwelling snakes typically inhabit rocky areas and gorges, where they shelter in rocks, caves, and hollow logs and prey on birds, mammals, and other reptiles.
Carpet python
- As with most pythons, they are heavy bodied, have a large head, and can grow up to several metres long
- The patterns on their scales can vary, but typically include bands of brown, black, and cream
They can inhabit a wide range of habitats from rainforest and dry woodland to suburban backyards and highly disturbed farmland, where they mostly feed on mammals.
Though they are not venomous, they can bite if provoked and cause significant lacerations or punctures.
Water python
- Can grow up to 2.5 metres long
- The scales on their back and sides have a rainbow sheen and can range from dark olive to black
- The scales on their underbelly can range from dull to bright yellow
Water pythons are non-venomous, semi-aquatic, and generally encountered close to rivers, creeks, and other freshwater sources. Here, they prey on a variety of animals, including rats, wallabies, and water birds.
Slaty grey snake
- Can grow up to 2 metres long
- The scales on their back and sides are shiny and can range from deep brown to a dark grey or charcoal
- The scales on their underbelly can range from white to cream
The Slatey grey snake is generally found in moist forests and open grass and woodlands with floodplains. Here, they shelter beneath rocks, logs, and leaf litter and prey on mammals, birds, and frogs.
Though they are not venomous, they can react aggressively and emit a foul odour if disturbed.
Death adder
- They have a short, stubby body that can grow up to 1.2 metres long
- They have a broad head with raised ridges above the eyes
- The scales on their back and sides can be variable in colour with contrasting bands
- The scales on their underbelly can range from cream to grey
Death adders are common in forests, woodlands, and heath, where they cover themselves with leaves to ambush frogs, lizards, and birds.
They are highly venomous snakes - in fact, before the introduction of antivenom, 60% of their bites to humans were fatal.
King brown (Mulga snake)
- Can grow up to 2.5 metres long
- The scales on their back and sides are large, defined, and can vary greatly from a pale brown to a rich reddish brown
- The scales on their underbelly can range from cream to white
The Mulga snake can occur in a broad range of habitats, from closed tropical monsoon forest to sandy desert. Here, they shelter in disused animal burrows, soil cracks, and under large rocks and feed mostly on vertebrate prey.
They are considered dangerous snakes, as their venom is highly toxic and can disrupt nerve, muscle, and red blood cells.
First aid
It is important to remember, snakes of the same species can vary dramatically in colour, pattern, and size.
As such, all snake bites should be treated as venomous until proven otherwise by a doctor at a hospital.
