Geographic range
editP. guttatus is endemic to the inland areas of south-eastern Queensland and north-eastern New South Wales, Australia.[3]
Habitat
editThe preferred natural habitats of P. guttatus are grassland, shrubland, and savanna.[1]
Description
editOn average, P. guttatus grows to a total length (including tail) of 1.2 m (3.9 ft), but some specimens have been found to measure as long as 1.5 m (4.9 ft).[3]
Diet
editP. guttatus is carnivorous. Its diet consists of frogs, lizards, and small mammals.[3]
Reproduction
editP. guttatus, like most other snakes, is oviparous, laying 7–12 eggs during the breeding season.[3]
Venom
editThe average venom ejection of P. guttatus is unknown. The snake's venom is the second most toxic of all the Australian black snakes. It is naturally very shy, and will not bite unless provoked (by being stepped on by a boot, prodded by a stick, etc.). A human, if bitten, may suffer severe pain, nausea, vomiting, diarrhoea, diaphoresis and regional lymphadenopathy at the location of the bite, similar to a red-bellied black snake's bite symptoms.[4] Bites are infrequent. If bitten, tiger snake antivenom is the preferred treatment.[5]
