SPOTTED OR BLUE BELLIED BLACK SNAKE Panacedechis guttatus (De Vis, 1905)
This snake varies in colour from black, to grey or whitish, with variable markings. It attains 1.5 metres and is found in drier habitats of the north east quarter of NSW, and south east Queensland. Although no deaths are recorded from the bite of this snake, it is fairly excitable and has potent venom, so should be regarded as dangerous.
The scalation is smooth with 19 mid body rows, 175-205 ventrals, divided anal, and 45-65 single and divided subcaudals.
This diurnal snake is more pugnacious than other members of the Black Snake family, hissing loudly and flattening out its' body when disturbed.
It occurs in a range of drier habitats, although in very dry areas this snake is usually found in the vicinity of water.
The Blue Bellied Black Snake feeds on small mammals, frogs and lizards. It produces 7-13 eggs. Incubation takes 11-12 weeks with hatchlings measuring about 28 cm.
