The Snouted Night Adder is very similar to the Rhombic Night Adder in appearance and behaviour, but is much smaller, averaging 35 cm, with a maximum length of 43 cm. It generally occurs further east than the Rhombic Night Adder, but their distributions do overlap.

This snake can be distinguished from the Rhombic Night Adder by its upturned snout. It hunts both during the day and night and is fond of basking in the sun. Like the Rhombic Night Adder, it feeds almost exclusively on frogs, particularly toads.

Snouted Night Adder venom is similar to that of the Rhombic Night Adder – cytotoxic, causing pain and swelling. Because of its size, the venom yield is less than the bigger Rhombic Night Adder and bites are seldom serious with swelling subsiding within a few days. Antivenom is not effective and not required.
