How to Identify the Persian Krait (Identification Guide)
Recognize the Persian Krait by its slender banded body, smooth scales, and arid-adapted range across Iran and neighboring parts of Southwest and Central Asia.

The Persian Krait is a slender elapid adapted to the drier landscapes of Iran and neighboring regions, distinguishing it from the more forest-associated kraits of South and Southeast Asia. It retains the classic krait shape: smooth cylindrical body, short tail, small head barely wider than the neck, and a raised row of enlarged vertebral scales along the spine.
Coloration & pattern
The body typically shows a dark brown to blackish ground color crossed by narrow, pale yellowish or whitish bands, which may be more widely spaced than in tropical krait species. Pattern contrast can vary regionally, with some populations showing more muted or incomplete banding. The venter is plain and pale.
Head, eyes & scales
The head is small, rounded, and uniformly dark, not strongly set off from the neck. Eyes are small with round pupils. Dorsal scales are smooth and glossy, and the enlarged hexagonal vertebral scale row is the most reliable feature for confirming this is a true krait rather than a similarly patterned colubrid.
Size & body shape
Adults generally reach 60 to 100 centimeters, with a slim, evenly rounded body and a short tapering tail, consistent with the elongated build typical of the genus.
Range & habitat where you'll see it
The Persian Krait inhabits semi-arid plains, foothills, agricultural oases, and areas near water sources across Iran and adjoining parts of Southwest and Central Asia. It is nocturnal and terrestrial, often encountered near irrigation channels or after rains.
How to tell it apart from look-alikes
In arid habitats it can be confused with banded racers or other colubrids, but the enlarged vertebral scale ridge and smoother, glossier scale texture distinguish true kraits. It lacks the hood of cobras found in overlapping range and the triangular head and keeled scales of vipers.
Frequently asked questions
How does the Persian Krait's banding compare to tropical kraits?
Its pale bands are often more widely spaced or muted compared to the crisp, dense banding seen in some tropical krait species.
What habitat does this krait prefer?
Semi-arid plains, foothills, and areas near water sources such as oases and irrigation channels.
How can I distinguish it from a racer snake?
Check for the row of enlarged hexagonal scales down the back, a trait unique to true kraits and absent in racers.
Is the Persian Krait active during the day?
No, it is primarily nocturnal, most active after dark or following rain.
Does it have a hood?
No, kraits never develop a hood; the head stays narrow and rounded.
