This elapid species typically reaches lengths of 1.5 to 2 metres and exhibits both diurnal and nocturnal activity patterns.
To identify a Dugite, you’ll need to observe its slender build, triangular head, and distinctive dark bands on the neck, while being cautious of common encounter scenarios such as in gardens, bushland, or near human settlements.
General Description
With its sleek profile and formidable venom, the dugite snake (Pseudonaja affinis) is a notable elapid species native to Western Australia. You’ll find dugite snakes characterised by their slender build and variable coloration, ranging from light olive to dark brown. Adult dugites typically measure 1.5 to 2 metres in length, with females generally larger than males.
The dugite’s head is relatively small and indistinct from its neck, featuring large eyes with round pupils. Its scales are smooth and glossy, contributing to its streamlined appearance. Baby dugites and juvenile dugite snakes often display banded patterns that fade as they mature, making identification challenging for inexperienced observers.
You’ll notice dugite snakes possess 17 rows of mid-body scales, a key identifying feature. Their ventral scales are pale, contrasting with their darker dorsal coloration. Dugites have short, fixed front fangs typical of elapids, which deliver their potent venom.
These snakes are known for their agility and speed, capable of swift movements when threatened or pursuing prey. Their adaptability to various habitats, including urban areas, contributes to their widespread distribution across Western Australia.
Average Length
In relation to average length, dugite snakes typically range from 1.5 to 2 metres when fully grown. This size makes them a formidable species among Australian elapids.
You’ll find that juvenile dugites are considerably smaller, usually measuring between 20 to 40 centimetres at birth.
It’s essential to understand that a dugite’s length correlates with its venom yield. Larger specimens can deliver more potent bites, increasing the severity of dugite venom effects.
When considering how poisonous dugites are, remember that venom potency doesn’t necessarily increase with size, but the quantity delivered does.
In the event of a dugite snake bite, the snake’s length can influence the amount of venom injected. Longer snakes generally have larger venom glands, potentially resulting in a more dangerous envenomation.
However, it’s significant to mention that dugites, regardless of size, are capable of delivering dry bites (bites without venom injection).
Understanding the average length of dugites is vital for identification purposes and evaluating potential risks.
Always maintain a safe distance, as even smaller dugites can strike rapidly and effectively, posing a significant threat if encountered in the wild.
General habits
The general habits of dugite snakes (Pseudonaja affinis) are closely linked to their size and environmental adaptations.
These elapids are primarily diurnal, exhibiting peak activity during daylight hours, especially in the cooler months. You’ll often find them basking in the sun to regulate their body temperature, a behaviour essential for their metabolic processes.
Dugites are terrestrial snakes, spending most of their time on the ground. They’re known for their agility and speed, capable of swift movements when threatened or pursuing prey. Their diet consists mainly of small mammals, reptiles, and occasionally birds.
You’ll notice they’re opportunistic feeders, adapting their hunting strategies to available food sources. During extreme temperatures, dugites may become crepuscular or nocturnal, shifting their activity patterns to avoid heat stress.
In winter, they’ll often enter a state of brumation, reducing their metabolism and activity levels. These snakes are typically solitary, coming together only for mating purposes.
You’ll find they’re excellent swimmers, utilising this skill to cross water bodies or escape threats. Their climbing abilities, while not exceptional, allow them to navigate low vegetation and rocky terrain effectively.
Identifying Eastern Dugite Snake
Identifying the Eastern Dugite Snake (Pseudonaja affinis) requires attention to several key physical characteristics. The snake typically measures between 1.5 to 2 metres in length, with a slender build. Its head is relatively small and indistinct from the neck, a common feature among elapid snakes.
The snake’s colouration can vary, but it’s often a uniform olive-brown to dark brown, sometimes with a coppery sheen. You’ll notice the snake’s scales are smooth and glossy, with 19-21 rows at mid-body. The ventral scales number between 190-220, while the subcaudal scales range from 55-70.
The snake’s eyes have round pupils, distinguishing it from pit vipers. Look for the absence of a loreal scale between the nasal and preocular scales, a characteristic of elapids. The Eastern Dugite’s tail is moderately long, tapering to a fine point.
You may observe faint, darker bands on younger specimens, which often fade as the snake matures. Be aware that colour and pattern can vary depending on the snake’s geographic location within its range in Western and South Australia.
