The first man to capture one of these cousins of cobras died the next day from a bite (in 1950). One species of this snake was thought missing for 80 years until rediscovered in the 1970s. That species of this snake holds the distinction of having the venom with the highest LD-50 of any snake in the world (even higher than any sea snake). Identify the more common name for the genus Oxyuranus, consisting of 4 deadly species all found in (shock!) Australia, which have a name which is similar to a Cantonese term for a business owner, particularly a foreign owner of a business around Hong Kong.
