Pseudonaja is a genus of highly venomous elapid snakes native to Australia.
Similarly, a trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Pseudonaja.
[5] Brown snakes are easily alarmed and may bite if approached closely, handled, or threatened.
[6] Other clinical signs include abdominal pain, breathing and swallowing difficulty, convulsions, ptosis, hemolysis, and hypotension from depression of myocardial contractility.
[7] Bites by the bigger species of Pseudonaja, especially P. textilis and P. nuchalis, are known for causing serious toxicosis and fatalities.
