Coagulation disturbance is common in brown snake bites, as is neurotoxicity.
Myolysis is not a feature of brown snake envenomation, although renal failure may ensue putatively as a result of direct nephrotoxicity or disseminated intravascular coagulation. The common brown snake is active mostly by day, except in very hot weather, and feeds on rats, mice, birds, lizards and other snakes. It is attracted to barns and farms, and prefers dry country to swampy areas. The brown snake lays from 10 to 35 eggs. The young brown snakes are banded in dark grey or black, and have a broad band on the back of their heads.
