Family :
ELAPIDAE
Species : Acanthophis spp.
Maximum Size : 1 metre Death Adders occur in a
variety of habitats including various forest types from sea level to around
1800 metres, grasslands, plantations and gardens. They lie well-concealed
amongst leaf-litter or grasses : if trodden upon they will not hesitate to
strike, and fatalities from Death Adder bites are a reality in much of rural
Papua New Guinea.
The various Acanthophis species appear to be nocturnal as well as
diurnal.
The genus is unmistakable in its appearance : the head is triangular and
viper-like, the body short and thick and the tail short.
The eyes are moderate in size, and above each a raised 'horn' is generally
present (a modified supraocular scale). The scales are smooth or
mildly keeled.
Dorsal patterning and colouration is variable, ranging from brownish to
greyish often with pale banding. The underside is generally pale, sometimes
with dark spots.
Death Adders will wriggle their short tail to lure their prey, which
includes lizards, birds and small mammals.
Acanthophis are widespread in PNG, and range
further afield to Indonesian Papua (formerly Irian Jaya), the Aru Islands
and parts of Australia.

area of Southern Highlands Province, PNG, at an elevation of 900
metres.
Fig 2 : Above the eyes, the raised supraocular scales form two distinctive
'horns'.

encountered on a manicured golf course at Timika, in the south of Papua
(Indonesian New Guinea). Photos thanks to Bill Mahnken.
