The eastern brown snake (Pseudonaja textilis), often referred to as the common brown snake, is a species of venomous elapid snake of the genus Pseudonaja. This snake is considered the world's second most venomous land snake based on its LD50 value (SC) in mice. It is native to Australia, Papua New Guinea, and Indonesia.orrell (1963) reported a milking of 41.4 mg from a relatively large 2.1 metres (6.9 ft) specimen. This record is atypical, as the eastern brown snake yields a low volume of venom which is reported as not more than 10 mg, averaging only 2 mg (dry weight).
